Gamers’ Self-Efficacy When Using English in School and When Gaming
Authors: Liverød Sara Barosen
Published: July 2022

The aim of this study is to examine the relationship between gamers’ and non-gamers’ self-efficacy when using English while playing video games at home and using English in the classroom. Data were collected through an online questionnaire distributed to 79 first-year upper-secondary students in Norway. The participants were divided into groups of self-reported gaming time per day: Frequent gamers (>3 h), Gamers (2–3h), Casual gamers (1–2h), and Non-gamers (0 h). The results show a statistically significant difference between Gamers (n = 11), Casual gamers, and Non-gamers in terms of self-efficacy. Gamers show a higher sense of self-efficacy when using English in the classroom (M = 39.45) and while playing video games (M = 39.9) than those who play either more or less. Higher self-efficacy correlates with higher grades in both settings (Classroom setting p = <.001; Gaming setting p = .010). There was no connection between being a gamer and their given grades (p = .337). The findings suggest that playing a moderate amount of video games in English can affect students’ self-efficacy positively in relation to using the language, both while playing and in the classroom. The findings also suggest that even though spending excessive time on video games might increase self-efficacy while playing, it cannot be transferred to the classroom. Background variables could not account for this difference. A secondary finding reveals clear gender differences in the amount of time spent on video games; further research is required in this field.

Os documentos revelaram que a identidade proposta para os cursos de Licenciatura sofreu variações de acordo com o contexto histórico e o cenário político nos quais essas Resoluções estão inseridas.
INFLUENCE OF USAGE AND CONTRACTUAL BINDS ON CUSTOMER RETENTION IN CONTINUALLY DELIVERED SERVICES: EVIDENCE FROM THE PHYSICAL FITNESS BUSINESS
Authors: Munaier Christian Gomes e Souza , Costa Cleverson Renato Moreira da
Published: July 2022

Attempts to preserve the bond with customers and to create means to increase firms captured value is a persistent management concern and subject of extensive academic research. From the service-dominant logic perspective, no value is created until the beneficiary of the service, often the customer, uses the products or services of a firm in its particular context. Therefore, the purpose of this paper is to show that there is a direct relationship between member usage and customer retention in continually delivered services. Data were extracted in the context of physical fitness business. The proposed model included price and membership length to evaluate membership renewal. Using logistic regression and unidirectional ANOVA, the results show that frequency of use was the most relevant variable related to customer retention. Surprisingly, price and membership length showed no impact on retention. We discuss these findings in the perspective of value creation.

Authors: Zenone Ana Carolina , Cezar Bruno Barbosa , Guevara Arnoldo de Hoyos
Published: July 2022

Given the still current scenario of disparity of opportunities regarding groups considered as minorities in several areas, such as education, income and work, cultural diversity in organizations remains relevant and fundamental in order to contribute to improve social conditions. To clarify the theoretical bias and encourage approaches on the topic, that is slowly gaining space, the basic concepts are first considered before going into the central focus of this work regarding potential organizational trends in the management of cultural diversity in Brazil and linked mainly to the processes of attraction and selection of talents. For this purpose, data from a recent survey of 109 Organizations in Brazil, allows to see how the concept management applied in an integral and uniform way in the organizational culture - and permeating all its processes – reflexes positively into business performance in addition to representing the practice of a social responsibility activity that is inherent to the subject. Moreover, results indicate the advantages in recruiting better talents, greater customer orientation, greater employee satisfaction and better decision making. This demonstrates that the gains reach, directly or indirectly, the organizational performance as a whole, and better, guided by principles that permeate an ethics of social responsibility that should be part of the organizational actions.

Published: July 2022

This research has the purpose to study the use of volunteer workmanship with the purpose of solving janitorial service problems in the city of São Paulo. By means of technology and human capital, it is expected to promote social and economic impact on target audience, i.e., individuals from peripheral and of low-income areas of the city. The research results demonstrate that the volunteer work practice is present in the society since the primordial years of small towns and cities and the Human Capital Theory evidenced the importance to use and educate the human workmanship, as, according to this theory, this is the major economical agent of transformation. Linking the historic context with the janitorial and maintenance problems found in the city, we get to the hypothesis of joining the volunteer work with care of public services, promoting social impact and urban transformation. These characteristics are fundamental to make the city smart. It was concluded that São Paulo does not have an efficient management nor an innovative management to solve the analyzed problems; therefore, it is essential to present proposals with alternative solutions, which in a simple manner may be able to improve the efficiency using more technology and promoting a social-economical impact.

How to properly apply new external knowledge
Authors: Salehi Nader
Published: July 2022

This article was an attempt to brief a new model of absorptive capacity and develop the concept of absorptive capacity which is a critical factor in applying, accumulating and linking new external knowledge to innovation. Through a comprehensive review of literature on absorptive capacity, authors ended up with the idea that the stream of new external knowledge in the waterfall model continually fosters all abilities of absorptive capacity. In addition, following knowledge spillover in each stage, abilities perform their activities. Knowledge accumulation is also another capability, which in this process, plays the role of linking absorptive capacity and innovation.

Published: July 2022

Background: Coronavirus disease 2019 (COVID-19) is a highly infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Large-scale vaccination of risk groups and later the general population is the single most effective public health measure for mitigation of the COVID-19 pandemic.

Methods and Materials: This prospective cross sectional study was carried out at Dhaka North City Corporation dedicated COVID-19 hospital, Mohakhali, Dhaka, enrolling 50 (fifty) vaccinated RT-PCR positive COVID-19 patients.

Results: Majority of the patients were >50 years old. Most of the patients had bilateral lung involvement and ground glass was the predominant CT pattern. 20% patients had consolidation in HRCT scan. Most of the patients (46%) had mild disease and only 18% patients had severe disease. Severe cases were more common (77.8%) in older (>50years) patients. 20% of the patients had 50-75% and only 6 % patients had more than 75% of total lung involvement. 52% patients had less than 25% lung involvement. Lung involvement was significantly higher in older patients. Patients had to stay an average of 6.2 days in hospital. Older patients had to stay more days in the hospital than younger patients. 2% (1) of COVID-19 patients died after admitting into our hospital.

Conclusion: Vaccination can effectively reduce mortality and morbidity of COVID-19 patients by reducing the active number of cases as well as severity of the disease.
Skin Barrier in Patients with Lichen Simplex Chronicus in the conditions of A COVID-19 Pandemic
Authors: Georgieva Filka
Published: July 2022

Background: The primary role of the skin is to protect the body from environmental factors. The intact skin is a barrier to the uncontrolled water loss, proteins and plasma components from the organism. Frequent hand and body wash has a negative impact on skin ecosystem by removing lipids which naturally preserve and protect it.
Objective: The purpose of this study is to evaluate changes in barrier functions of skin in the condition of repeated body and hand wash in Lichen Simplex Chronicus (LSH) patients.
Materials and Methods: Transepidermal Water Loss (TEWL) and Hydratation (H) of epidermis in healthy and damaged skin were measured in 36 non-hospitalized LSH patients. The results were compared with those from a similar study but in patients before the COVID pandemic recommended hygiene regimen.
Results: The results reported in the present study showed significantly more pronounced skin barrier disorders compared to those announced in LSH patients before the COVID pandemic.
Conclusion: All the reported and analyzed results indicate that disorders of skin barrier are connected with severity and duration of LSH. The frequent washing regime act as an additional reduction of the barrier function of the skin and thus worsens the parameters of the disease.

The dynamics of the Omicron variant in India, Mumbai, and Delhi have been studied. The % share of the Omicron variant in overall India rose from 0.35% to 97.12% during the period November 29, 2021, to February 7, 2022. Due to the emergence of the Omicron variant, the daily new infections in India rose from a baseline tally of below 8,000 cases to the highest number of 347,063 cases recorded on January 20, 2022. In Mumbai, the Omicron variant completely replaced the Delta and other lineages as reported on March 3, 2022 genome sequencing report. In Mumbai because of the Omicron variant surge, the new infections rose to 20,971 on January 7, 2022, from a baseline tally of 191 daily cases recorded after receding the second Delta variant wave. In real-time, the vaccine effectiveness among the Indian population during the Omicron variant surge was studied and noticed that the two-dose regimen was 99.3% effective in preventing death. The death rate among the hospitalized patients was reduced by 12% among the vaccinated individuals compared to the unvaccinated ones. During the Omicron variant wave, the average age of the COVID-19 patients shifted by 11 years towards the younger age which was because the vaccination among the younger population was low compared to the elderly population.

One of the many options of geographical education is field teaching. Thanks to the direct contact of pupils with the country and specific examples of human activity in it, pupils have the opportunity to understand better the interconnectedness of various phenomena and components in the country and build a positive relationship to its natural and social values. Another reason for using field teaching is the possibility of applying interdisciplinary relationships, while on the example of a mining country, it is possible to integrate information, topics and procedures from geography, geology, history and other subjects. The importance of field teaching also lies in the practical use of knowledge and skills pupils have acquired at school. It also gives more space for group work, communication, strengthens social relations. Field teaching of geography at primary and secondary schools has its place also within the current school curriculum. Nevertheless, teachers include this method in the teaching only to a limited extent. The paper presents the mining village of Špania Dolina near Banská Bystrica, its potential in science and social education, and the design and experience with the implementation of field teaching in this village.
KUTADGU BİLİG DE BARIŞ, SAVAŞ VE DÜŞMAN ALGISI
Authors: Sarı Şeyma
Published: July 2022

Edebi eserler sanatçının bir olayı, olguyu, durumu ya da nesneyi nasıl algıladığını gösteren sanatsal ifadelerdir. Klasik Türk edebiyatının bilinen ilk mesnevisi Yusuf Has Hacip’in 11. yüzyılda yazdığı Kutadgu Bilig eseri de ideal bir devletin, toplumun ve insanın nasıl olması gerektiğini anlatması yönüyle bir siyasetname olarak karşımıza çıkar. Eser aynı zamanda “barış”, “savaş”, “düşman” ve “düşmanlık” kavramlarına ışık tutan kuramsal bir mesnevidir. Bu çalışmanın amacı Kutadgu Bilig’de barış, savaş ve düşman kavramlarının nasıl ortaya konulduğunu incelemektir. Ayrıca “barış, savaş, düşman ve düşmanlık” konusunda daha önce yapılmış çalışmalara farklı bir bakış açısı sunmak, böylece alanı genişletmektir. Bu düşünceden hareketle edebi eserlerin savaş ve barış gibi toplumsal meselelere farklı bir bakış açısı kazandırdığını örnekleriyle ortaya koymak da gerekir. Çalışma üç bölümden oluşmaktadır. Birinci bölümde “Kutadgu Bilig’e göre barışın anlamı”, ikinci bölümde “Kutadgu Bilig’e göre savaşın anlamı” anlatılmıştır. Üçüncü bölümde ise “düşman ve düşmanlık” kavramlarının Yusuf Has Hacip’e göre nasıl anlaşıldığı araştırılmış ve bununla ilgili beyitler ele alınıp açıklanmıştır. Kutadgu Bilig’de fertlerin, toplumların ve devletlerin uzun süre ayakta kalabilmesi için gerekli olan nitelikler sıralanmıştır. Devletin düzenini ayakta tutan en önemli şey insanlar arası güvenin tesis edilmesidir. Devletin idaresini elinde tutanlar iç ve dış düşmanlarını iyi tanımalı ve düşmanı her yönüyle takip etmelidir. Bu, halkın da emniyet ve huzur içerisinde yönetilmesi için gereklidir. Bu çalışma “Kutadgu Bilig’e göre düşman çeşitleri nelerdir, bu düşmanlarla nasıl mücadele edilmelidir, kimlerin düşmanı çok olur, düşmanın zararları nelerdir, düşmanı olmak her zaman kötü bir şey midir ya da insana düşmanın faydası olabilir mi?” sorularını da cevaplamaktadır.

Authors: Karthigaiselvi Dr.G.
Published: July 2022

Salman Rushdie is one of the most important postcolonial writers in English literature. Through his literary contributions, he ushers in a new era of postcolonial literature. Rushdie is a world-renowned novelist whose outstanding works have garnered him accolades, thrills, and controversy throughout his illustrious career. Several Indian authors, including Amitav Ghose and Rohinton Mistry, have been greatly influenced by his unquestionable creativity. As one of the world’s most controversial and provocative contemporary novelists, Salman Rushdie stands out. Postcolonial and postmodern writers like Gabriel Garca Márquez, Günther Grass, Milan Kundera, and Jorge Luis Borges were considered to be among his contemporaries during the 1980s and 1990s. Allegory, multiculturalism, magic realism and other postcolonial techniques are used in Rushdie’s works to create alternative views of the colonial situation in a postcolonial context.

Blood type as biological information is still considered a prophecy and pseudoscience that still needs to be proven. It is the easiest and cheapest among other genetic identification tools.This study aimed to map reading material selections based on blood type personality. This study was a quantitative approach through cross-sectional survey. Identification was obtained from data in identity cards and laboratory blood type tests. The study population was 100 UPI LIS students with 80 samples of young adults aged 18-22 through random sampling with stratification. The samples were: 9 respondents with AB blood type and 25 with A blood type. Respondents of O and B blood types each followed the selection of the expected sample was 20 people. Each homogeneous sample filled out a questionnaire on reading material selection aspects. Results showed that 55.6% of the AB blood type chose non-fiction books such as 'how-to' related to hobbies, and 52% of A blood type tended to select non-fiction books that support their tasks and work. Also, 81.8% of B blood type chose fiction books and adventure stories opening up fantasy horizons, and 80% of O blood type chose books that did not always have to be brought to the big screen/filmed; however, they were recommended and told. In conclusion, this blood type personality model can identify young adult clients' profiles to develop bibliotherapy service programs in different types of libraries and make it easier for librarians and bibliotherapists to recommend reading materials suitable for the benefit of preventive-curative bibliotherapy.

An Electrolytic Capacitor-Less PV Micro-Inverter Based on CLL Resonant Conversion With a Power Control Scheme Using Resonant Circuit Voltage Control Loops
Authors:   York University - Keele Campus, Kanathipan Kajanan
Published: July 2022

A power control scheme with maximum power point tracking based on solely voltage feedback control loops is proposed in this paper for a dc/ac isolated high frequency PV micro-inverter. The presented power circuit topology consists of an integrated continuous conduction mode (CCM) boost converter with an asymmetrical pulse-witch modulation (APWM) controlled CLL step-up resonant converter and a half-bridge grid-side inverter. The presented topology is capable of achieving CCM input current and a wide range of zero voltage switching (ZVS) operation for the front-end stage. The proposed power control scheme, as well as the developed maximum power point tracking (MPPT) control technique utilize the resonant circuit’s resonant capacitor voltage and the APWM input voltage of the resonant circuit only to achieve MPPT and to control the active power of the overall system. By doing so, a large electrolytic input filtering capacitor is not needed. This allows small size film capacitors to be used and improves the system lifetime expectancy. The theoretical analysis and the detailed descriptions of the proposed power control scheme for the presented PV micro-inverter are provided. Simulation and hardware results on a 220 W with 120 Vac, 60 Hz output hardware prototype are presented to demonstrate the performance of the proposed PV inverter system.
Healthy nonobese bitches maintain acceptable spontaneous ventilation during laparoscopic ovariectomies
Authors: Merlin Tristan , Cinti Filippo , Charlesworth Tim M.
Published: July 2022

OBJECTIVE

To determine whether end-tidal CO2 (Petco2), tidal volume (Vt), inspiratory minute volume (i), and respiratory rate (RR) remain within reference limits for spontaneously breathing dogs undergoing laparoscopic ovariectomy; characterize changes in these variables over time; and record the proportion of dogs requiring mechanical ventilation on the basis of predetermined criteria.

ANIMALS

22 client-owned dogs.

PROCEDURES

Between January and June 2019, dogs were anesthetized for abdominal insufflation (CO2; 10 mm Hg) and laparoscopic ovariectomy. Respiratory variables (Petco2, Vt, i, and RR) were recorded at 5 time points: preinsufflation (T2), immediately after insufflation (T3), immediately after first ovary extraction (T4), immediately after second ovary extraction (T5), and after abdominal deflation (T6). Results for variables were assessed to identify differences with reference limits and between time points.

RESULTS

At all time points (T2 to T6), Petco2 was within or above the reference limit, Vt was below or within reference limits, and i was either within or above reference limits. Significant temporal changes were detected in all recorded parameters. One dog had to be ventilated prior to abdominal insufflation due to inappropriately low Vt (< 6 mL/kg) and was excluded from further analysis. One of the 21 remaining dogs required rescue ventilation.

CLINICAL RELEVANCE

Following insufflation, there was a tendency toward inadequate ventilation over time characterized by increased Petco2. Twenty of 21 dogs maintained Petco2 within tolerance via a mild increase in RR and did not require assisted ventilation. Dogs undergoing short surgeries may not require assisted ventilation. Clinicians are advised to monitor for hypercapnia and be prepared to assist ventilation if required.

Published: July 2022

OBJECTIVE

Merck Animal Health Veterinarian Wellbeing Study III was conducted to continue to monitor mental health and well being within the veterinary profession in the US and to identify factors associated with high levels of wellbeing and lack of serious psychological distress.

METHODS

A questionnaire consisting of several instruments and questions for measurement of mental health and wellbeing was completed by 2,495 veterinarians and 448 veterinary support staff. Results for veterinarians were weighted to the US AVMA membership.

RESULTS

This study revealed that wellbeing and mental health of some veterinarians declined over the past 2 years, driven in part by the COVID-19 pandemic and extreme labor shortages. Burnout remained at a high level, but there was no increase in suicide ideation. A new companion survey of veterinary support staff demonstrated that staff scored lower in wellbeing and mental health, and higher in burnout than veterinarians.

CLINICAL RELEVANCE

Importantly, these studies identified techniques that both individuals and employers may find useful in fostering wellbeing and good mental health. A healthy method for coping with stress and good work-life balance was important, as was engaging a financial adviser for those with student debt or other financial stresses. Employers should create safe environments where employees feel comfortable seeking help, reducing the stigma associated with mental health issues. In addition, employers can provide Employee Assistance Programs and health insurance that covers mental health treatment. Fostering a healthy work culture was also important, one with good communication, teamwork, trust, and adequate time allotted to provide quality patient care.

Published: July 2022

The hygienic behavior in honey bees is a complex polygenic trait that serves as a natural defense mechanism against bacterial and fungal brood diseases and Varroa destructor mites infesting brood cells. The aim of this study was to evaluate the effect of a dietary amino acids and vitamins supplement “BEEWELL AminoPlus” on hygienic behavior of Apis mellifera colonies combating microsporidial and viral infections. The experiment was performed during a one-year period on 40 colonies alloted to five groups: one supplemented and infected with Nosema ceranae and four viruses (Deformed wing virus - DWV, Acute bee paralysis virus - ABPV, Chronic bee paralysis virus - CBPV and Sacbrood virus – SBV), three not supplemented, but infected with N. ceranae and/ or viruses, and one negative control group. Beside the l isted pathogens, honey bee trypanosomatids were also monitored in all groups.

The supplement “BEEWELL AminoPlus” induced a significant and consistent increase of the hygienic behavior in spite of the negative effects of N. ceranae and viral infections. N. ceranae and viruses significantly and consistently decreased hygienic behavior, but also threatened the survival of bee colonies. The tested supplement showed anti-Nosema effect, since the N. ceranae infection level significantly and consistently declined only in the supplemented group. Among infected groups, only the supplemented one remained Lotmaria passim-free throughout the study. In conclusion, diet supplementation enhances hygienic behavior of honey bee colonies and helps them fight the most common infections of honey bees.
Pilot Study of Invasive Mosquito Species Control in Selected Slovenian Municipalities

Published: July 2022

To reduce the population of the Asian tiger mosquito Aedes albopictus (Skuse, 1894) (Diptera: Culicidae), a mosquito control campaign was organized by five Slovenian municipalities in 2020. The campaign focused on the application of Aquatain AMFTM in public water containers. The main objective of our study was to test the efficacy of the agent by directly testing the water drains for mosquito larvae and monitoring the density of the mosquito population. The drains were inspected before and after the application of the product from May to September. A water sample was taken from the drains using a dipper. For mosquito monitoring, the number of mosquito eggs and adult mosquitoes was counted from June to October.

Up to two weeks after the application of the product, we observed the lethal effect of Aquatain on mosquito larvae, pupae and adult mosquitoes. After rainfall, the product was washed away and the live mosquitoes were sampled in the inspected water drains. The average number of eggs collected per site was twice as high in the area without mosquito control as in the threated locations. Nevertheless, we assessed the mosquito control campaign as partially successful, as mosquito abundance was still high in the locations with mosquito control. However, we believe that this is a good starting point and that mosquito control should be continued in the future together with the citizen education campaign.
Experimental and Numerical Small Punch Tests of the 14Cr ODS Ferritic Steel
Authors: Nowik Krzysztof , Oksiuta Zbigniew
Published: July 2022

Nowadays, various small specimen test techniques have gained wide popularity and appreciation among researchers as they offer undoubtful benefits in terms of structural material characterisation. This paper focuses on small punch tests (SPTs) performed on small-sized disc specimens to assess the mechanical properties of 14Cr oxide dispersion strengthened (ODS) steel. A numerical model was established to support experimental data and gain deeper insight into complex strain states developing in a deformed specimen. Modern evaluation procedures were discussed for obtaining mechanical properties from the small punch force-deflection response and were compared with the literature. Applicability and universality of those relations at different test conditions were also studied. It appeared that different ball diameters used had negligible influence on yield point but strongly affected ultimate strength estimation. It was found that friction belongs to decisive factors determining strain distribution in samples, as dry conditions increase the peak strain and move its location farther from the punch pole.

This article presents simulation models of trailer air brake systems in configurations without a valve and with a differential valve, thus demonstrating the rationale for using a valve to improve system performance. Simplified mathematical models using the lumped method for systems without and with a differential valve are presented. The proposed valve can have two states of operation depending on the configuration of relevant parameters. These parameters can include the length of the control pipe, the throughput between chambers in the control part of the valve and the forcing rise time. Based on the calculations, it was found that the differential valve with large control pipe lengths can reduce the response time of the actuator by 42.77% relative to the system without the valve. In the case of transition of the valve to the tracking action, this time increases only by 9.93%. A force rise time of 0.5 s causes the transition of the valve from the accelerating action to the tracking action, with 9.23% delay relative to the system without a valve. The calculations can be used in the preliminary assessment of the speed of operation of pneumatic braking systems and in the formulation of guidelines for the construction of a prototypical differential valve. In conclusion, it is suggested to use a mechatronic system enabling smooth adjustment of the flow rate between chambers of the control system of the differential valve.

“Rejuvenation of population” is commonly considered as an increase in the proportion of young individuals in the population. In our opinion, the term “rejuvenation” has to be used in case of an increasing percentage of young individuals providing maintenance or increase of the entire population size. In return, an increasing percentage of young individuals while reducing the number of the entire population should be considered as “pseudo-rejuvenation.” A key feature of rejuvenation is the positive dynamics of the population. Instead, pseudo-rejuvenation is an indicator of negative exogenous or endogenous changes and is evidence of population degradation under adverse environment conditions. The article presents the most common examples of the processes of rejuvenation of populations in different plant species under the influence of anthropogenic and natural factors in the plant communities of the Ukrainian Carpathians. The main causes of rejuvenation and pseudo-rejuvenation of populations of the target plant species have been identified. Studies of population structure changes in situ were performed using both long-term monitoring transects laid 5–40 years ago and in new sites. Transects are located in the alpine, subalpine, and upper forest zones of the Ukrainian Carpathians in the height range of 1200–2000 m a.s.l. The study areas cover the most common alpine and chionophilic communities, some forest and subalpine phytocenoses.
Parasocial relationships and YouTube addiction: The role of viewer and YouTuber video characteristics
Authors: de Bérail Pierre , Bungener Catherine
Published: July 2022

YouTube is a popular social media platform that fosters the development of social bonds between viewers and YouTubers called parasocial relationships (PSR). These relationships might be associated with both viewer characteristics, such as social anxiety, and YouTuber video characteristics, such as self-disclosure. Additionally, PSR might be associated with the level of addiction to the platform. Data from 370 college students were extracted from a previous study and 360 videos of 72 YouTubers were coded to (a) explore the different dimensions of PSR and (b) examine a mediation model of YouTube addiction. The results support the existence of three PSR dimensions. The results also showed that PSR dimensions were associated with both viewers’ social anxiety and YouTubers’ evaluative self-disclosure. One PSR dimension was positively associated with YouTube addiction. This study encourages the development of qualitative studies to more precisely identify the different facets of PSR with social media figures.

Background

The aim of the study was to analyze the association between the liver uptake of Gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) in the hepatobiliary phase (HBP) in cirrhotic patients and the presence of clinically significant portal hypertension (CSPH), and how these features impact on hepatocellular carcinoma (HCC) detection in the HBP.

Patients and methods

Post-hoc analysis of a prospective cohort of 62 cirrhotic patients with newly US-detected nodule between 1–2 cm (study group). Twenty healthy subjects were used as control group. Qualitative and quantitative analysis of the liver contrast uptake in the HBP assessed by Relative Liver-Enhancement (RLE), Liver-Spleen (LSCR), Liver-Muscle (LMCR), and Liver-Kidney Contrast-Ratio (LKCR), Contrast Enhancement Index (CEI), and Hepatic Uptake (HUI), and biliary excretion, were registered. CSPH was confirmed invasively (HVPG > 10 mmHg) or by indirect parameters. The appearance of HCC at the HBP was analyzed.

Results

Nineteen patients (30.6%) did not have CSPH. In 41 patients (66.1%) the final diagnosis was HCC. All indices were significantly higher in the control group, indicating a more intense HBP liver signal intensity compared to patients with cirrhosis, even if the comparison was restricted to patients with no CSPH. CSPH was associated to a lower rate of HCC hypointensity in the HBP (51.9% vs. 85.7% without CSPH, p = 0.004).

Conclusions

Liver uptake of Gd-EOB-DTPA at the HBP is decreased in cirrhosis even if the liver function is minimally impaired and it falls down significantly in patients with CSPH compromising the recognition of hypointense lesions. This fact may represent a limitation for the detection of small HCC in patients with cirrhosis and CSPH.
The Impact of Neoliberalism on Models of Science Communication
Authors: Krynzhina M. D.
Published: July 2022

National science is being transformed under the influence of global processes, which are mainly, although not entirely, dictated by the dominance of neoliberal ideas in a wide range of developed and developing countries. The term neoliberalism, (or neo-liberalism), which was coined in the 20th century, offers recommendations that include a set of political, economic, and ideological actions. The article examines the impact of the neoliberal turn in science on the process of interaction between science and society. It is substantiated that this affects the development of vector models for the spread of scientific neoliberal ideology. Academia is a research field that deals with a wide range of issues from actual dissemination of scientific research to the models of involving new constituencies, in which non-professionals are encouraged to participate in research via scientific discussions and polls. Academia is a global and debatable topic to be discussed. It should be noted that scientific communications as a process of promoting scientific knowledge outside the scientific communities have not been thoroughly studied by domestic researchers yet. In the international scientific community and the Russian scientific field, until recently, the understanding of the tasks of scientific communication varied greatly. However, the development of scientific communities is widespread in different countries and reveals the impacts of neoliberalism research on this process. The neoliberal initiative encourages the creation of conditions in which, firstly, citizens take an active part in solving scientific issues. And secondly, the prestige of the pursuit of pure science does not deter researchers from promoting commercialization and the free development of their scientific activity. The peculiarities of interaction between science and society are regarded from the point of view of the Italian sociologist Massimiano Bucchi. Distinguished in academic discourse for his classification of relationships among science, technology, and society, M. Bucchi specifies three patterns for such relationships: deficit, dialogue, and completion.
The Culture of Student Debate: When not to Argue

Published: July 2022

Today public speaking as a form of communication calls for the development of actives ways of speaker’s interaction with the audience, with the audience taking on an increasingly active and meaningful participation. In the cultural environment of modern higher education, in universities, student debates are becoming one of the most relevant and popular activities. Basing on the assumption that debate is an effective tool for developing both communicative and speech skills of future professionals in any field of activity focused on social interaction, this study aims to investigate the specifics of the organizing and conducting debates to develop mastery, professionalism, and leader potential of students in the framework of the course of Russian as a second foreign language (RSL). With this approach in mind, we set the following objectives: 1) to clarify the main approaches to the meaning of oral communication and the role of debate in it for the formation of basic competencies of students today; 2) to study the structure of typical units of public speaking; 3) to identify problems students face in the process of verbal communication; 4) to substantiate the advantages of using debates for the development of the necessary general cultural, professional and communicative qualities and skills of a future professional. In its methodology, this study was based on the works in the field of the theory of communication, the language of business communication, the culture of speech, pedagogy, and methods of teaching the Russian language to non-native speakers. The research methods included surveys and interviews, as well as content analysis and case study methods. The study has proved that solving the pedagogical problems of fostering responsibility, independence, and proactive social attitude requires the development of general cultural, research and communication skills, and debates have proved to be an effective form of practicing these skills in the educational process. The communicative culture and the overall training of students for their future professional career means leadership development, and for this cause debates are an effective teaching tool.
