Limitations of atomistic modeling to reveal ejection of proteins from charged nanodroplets
Authors: Kwan Victor , Ballaney Pranav , Titiksha Titiksha , Consta Styliani
Published: February 2023

Molecular dynamics using atomistic modeling is frequently used to extract the mechanisms of macroion release from electrosprayed droplets. However, atomistic modeling is currently feasible for only the smallest window of droplet sizes that omits the droplet history. The relevance of the observations made in this narrow window to the actual droplet evolution has not been addressed. Here, we perform a systematic study of desolvation mechanisms of poly(ethylene glycol) (PEG), protonated peptides of different compositions and protonated proteins in order to examine whether atomistic modeling can establish the extrusion mechanism of proteins from droplets. Atomistic modeling of PEG charging shows that above a critical droplet size charging occurs transiently by transfer of ions from the solvent to the macroion, while below the critical size, the capture of the ion from PEG has a lifetime sufficient for extrusion of the charged PEG from an aqueous droplet. This is the first report of the role of the droplet curvature in the charging of macroions. Modeling of the process in droplets of various sizes allow us to extrapolate the charging mechanisms in systems that cannot be modeled atomistically yet. Simulations even with highly hydrophobic peptides show that partial extrusion of a peptide from the droplet surface is rare relative to desolvation by drying-out of the protonated peptide. Differently from what has been presented in the literature we argue that atomistic simulations have not sufficiently established extrusion mechanism of proteins from droplets and their charging mechanism. Moreover, we argue that release of highly charged proteins can occur in earlier stage of a droplet's lifetime than that that is atomistically modeled. In this earlier stage, we emphasize the key role of jets emanating from a droplet at the point of charge-induced instability in the release of proteins.
Characterisation of magnetic relaxation on extremely long timescales

Published: February 2023

The use of magnetisation decay measurements to characterise very slow relaxation of the magnetisation in single-molecule magnets are becoming increasingly prevalent as relaxation times move to longer timescales outside of the AC susceptibility range. However, experimental limitations and a poor understanding of the distribution underlying the stretched exponential function, commonly used to model the data, may be leading to misinterpretation of the results. Herein we develop guidelines on the experimental design, data fitting, and analysis required to accurately interpret magnetisation decay measurements. Different measures of the magnetic relaxation rate extracted from magnetisation decay measurements of [Dy(Dtp)2][Al{OC(CF3)3}4], fitted using different combinations of fixing or freely fitting different parameters, are compared to those obtained using the innovative square-wave “waveform” technique of Hilgar et al, which is comparable to AC susceptometry for measurement of relaxation rates on long timescales. The most reliable measure of the relaxation time for magnetisation decays is found to be the the average logarithmic relaxation time, $e^{⟨ln [τ]⟩}$, obtained via a fit of the decay trace using a stretched exponential function, where the initial and equilibrium magnetisation are fixed to first measured point and target values respectively. This new definition has causes the largest differences to traditional approaches in the presence of large distributions or relaxation rates, with differences up to 50% with β = 0.45, and hence could have a significant impact on the chemical interpretation of magnetic relaxation rates. A necessary step in progressing towards chemical control of magnetic relaxation is the accurate determination of relaxation times, and such large variations in experimental measures stress the need for consistency in fitting and interpretation of magnetisation decays.
HEDGING THROUGH THE USE OF IMPERSONAL CONSTRUCTIONS IN INDONESIAN OP-ED ARTICLES
Authors: Yusnia Devi Nailis , Hardjanto Tofan Dwi
Published: February 2023

The presence of an opinion editorial (op-ed) page has provided room for the public to articulate their ideas about the recent salient issues at no cost. The notion that the authors of an op-ed article could express their ideas and arguments in public space makes them need certain devices like hedges to protect themselves from any negative consequences such as rejection from readers if in fact their argument is considered false. This article is intended to investigate the use of impersonal constructions as hedging devices in 45 Indonesian opinion editorial articles published by three leading national newspapers: Kompas, Tempo, and Republika. Impersonal construction in this case refers to a grammatical construction that avoids the use of a human subject in the sentence. This construction includes the use of agentless passive voice and abstract rhetors. A qualitative research design is applied in this study. This study reveals 56 occurrences of impersonal construction with details of 53 data belonging to the agentless passive voice category and 3 data belonging to the abstract rhetors category in the 45 articles examined.Â  The use of such constructions in op-ed articles can be a means to protect the authors from the consequences of being blamed if in any case, the argument they stated is different from the reality. Furthermore, this construction can also be used to avoid the subjectivity of the claim and direct the focus of the argument to the content of the text and not the authors.Â

Published: February 2023

This study aims to describe the development of the Balinese language from the Old Balinese period to the present as a diachronic study of language. The source of the data is obtained through a literature study, namely looking for references that are considered relevant to the problem under study. The theoretical approach used is a historical linguistic approach through diachronic language studies and the methodological approach uses a qualitative descriptive approach. The results of this study show that Balinese vocabulary is influenced by various languages including Sanskrit, Old Javanese, Dutch, English, Portuguese, Chinese, and Arabic. Vocabulary from other languages is fully absorbed and some are experiencing changes from the original vocabulary. Absorption of vocabulary from other countries cannot be separated from interactions that occur with Balinese people, such as trade relations, colonialism, and the spread of religion.
Examining the Imperative Clauses in Manggarai
Authors: Salahuddin Salahuddin
Published: February 2023

Manggarai is one of the languages in West Flores studied by many researchers, either native or non-native speakers. Nevertheless, only a few describe the sound system in the imperative clauses of the Manggarai language. Imperative clauses are speech acts intended to influence the interlocutor to take specific actions and aim to give orders (commands), requests, requests, suggestions (advice), warnings, instructions, and hopes. Some researchers who briefly describe imperative clauses have failed to formulate case markers in imperative clauses. Thus, this study aims to formulate case markings in imperative clauses comprehensively. Researchers as native speakers of the Manggarai language in the Kempo dialect use familiar examples. The data used in this study are examples of imperative clauses that are often found and assessed based on the author's intuition as a native dialect speaker. This study also tested several formulas of imperative clause rules in previous research, which distinguished the use of gi and ga, and neka marker in negative imperative clauses. Some critical findings in this research are, firstly, the markers gi and ga are not an enclitic attached to the word they follow; secondly, the articles gi and ga are not specific markers for imperative clauses because they can also appear in other clause forms (e.g., declarative clauses); and third, the words neka and asi in the negative imperative clauses of the Manggarai language can be used interchangeably and do not change the meaning of the clause. Thus, this proves that there are no unique markers in the imperative clauses of the Manggarai language because the form varies relatively depending on the context with whom one is talking.

The purpose of the study was to investigate the morphological properties of oral fluid in dynamics in the application of the developed set of measures for the prevention of fissure caries of the first permanent molars in children. Materials and methods. 62 children aged 6 years with fissure caries of the first permanent molars (main group) and 31 children without signs of carious lesions (control group) were examined. The study of the crystal formation of oral fluid was carried out according to the method of Leus P. A. (1977). The mineralizing potential of oral fluid was expressed as an average score depending on the types of crystals detected. Results and discussion. The analysis of the results of the study showed that 6 months after the start of preventive measures in the oral fluid of the children of the main group, a slight increase in type I crystals was noted in comparison with the initial data (40.18 ± 4.65% of cases, p>0.5), at the same time, the number of children, in whom type III crystals were observed, decreased in the main group (16.45 ± 2.32%, p>0.5), and increased in the control group (19.32 ± 2.47% of cases, p>0.5) in comparison with the initial data. After two years of observation, in the children of the main group, type I crystals were most often detected in the oral fluid (48.41 ± 4.23% of cases), in the children of the control group, on the contrary, the number of children with this type of crystals decreased and was almost one and a half times less than among children of the main group (p<0.05). On the other hand, the number of children in the control group, in whom type III crystals were detected, was two times higher than among children in the main group (22.34 ± 2.87% and 11.51 ± 2.56% of cases, respectively, p<0.05). Conclusion. It was established that in children who received a complex of preventive measures, 6 months after the implementation of preventive measures, the mineralizing potential of oral fluid was, on average, 2.73 ± 0.07 points, which is slightly higher compared to the fissure detected at the beginning of caries prevention (2.57 ± 0.12 points respectively, p>0.05). In the children of the control group, the mineralizing potential of oral fluid changed less noticeably (from 2.64 ± 0.11 points at the beginning of observation to 2.66 ± 0.11 points, p>0.5). After two years of observation, it was found that in the main group the mineralizing potential of oral fluid continued to increase, while in the children of the control group it decreased and reached almost the initial level (2.65 ± 0.07 points in the second year of observation and 2.64 ± 0.08 points at the beginning, p>0.05). Thus, it can be concluded that the proposed measures are quite effective

The purpose of the study was a comparative clinical evaluation of direct cervical restorations of teeth made from different materials. Materials and methods. In 49 patients aged from 22 to 37 years, direct restoration of 97 teeth with cervical carious lesions was carried out. Group 1 included 19 people (39.6% of the number of examined) with 35 restorations (36.1% of the number of restorations) from photocomposite, group 2 – 14 people (29.2%), in whom 34 restorations were performed (35.1%) with glass ionomer cement, in 15 patients (31.3%) of group 3 28 restorations (28.9%) were performed with chemically hardening composite. The examination was carried out the next day, after 6 and 12 months according to clinical and aesthetic criteria. Results and discussion. The next day, in patients of group 1, 2 restored teeth (5.7% of their number in patients of the group) had increased sensitivity. After 6 months, 1 restoration (2.9%) was missing in patients of group 1, 2 restorations (5.7%) had marginal fit violations, 1 (2.9%) – had marginal coloration, and 1 restored tooth (2.9%) was diagnosed with hypersensitivity. In patients of group 2, in 5 restorations (14.7%) defects of marginal fit and marginal coloration were detected. In persons of group 3, in 3 restorations (10.7%) the marginal fit was violated, in 4 (14.7%) – coloration. In the period of 12 months, in persons of group 1, 1 restoration (3.2% of their number at this time) was again absent, secondary caries was detected, defects in the marginal fit of the photocomposite were recorded in 3 restorations (8.6%), marginal coloration – in 4 (11.4%). In patients of group 2, in 6 restorations (22.2% of the number in this period), the marginal fit of the glass ionomer was violated, in 8 (29.6%) – marginal coloration. In patients of group 3, defects in the marginal fit of the chemical composite were identified in 7 restorations (29.2% of the number in this period), marginal coloration – in 6 (25%), secondary caries was found along with 1 restoration (4.2%). The undisputed dominance of the photocomposite material in the aesthetic evaluation of the state of restorations was proven, in particular, according to criteria that included color matching and surface roughness, only single deviations were found in photocomposite restorations, and in restorations from glass ionomer cement and chemically hardening composite, they were found several times more. Conclusion. When using photocomposite material to restore teeth with cervical carious lesions, the possibility of the abfraction effect with subsequent loss of restorations and the increased risk of postoperative sensitivity in the restored teeth should be taken into account

Published: February 2023

The purpose of the study was to consider the main methods of increasing the physical activity of people with disabilities (in wheelchairs) in emergency situations, military conflicts, natural disasters, etc. Materials and methods. The study of physical rehabilitation of people with disabilities (in wheelchairs) was conducted by the author during many years working as a trainer of the Kyiv Regional Center for Physical Culture and Sports for the Disabled “Invasport” and continued during the military actions in the country in 2022–2023 with an emphasis on the problems of rehabilitation of patients in military and emergency conditions. In order to increase the physical activity of people with disabilities (in wheelchairs) in conditions limited by military operations, it is recommended to pay special attention to exercises for the muscles of the neck, joints, and muscles of upper limbs; exercises for the lower limbs and pelvic organs; exercises for back and trunk muscles; balance exercises, breathing exercises, etc. Massage and self-massage procedures will also be useful in such situations. Results and discussion. The effectiveness of rehabilitation and, as a result, the successful outcome of maintaining the physical activity of people with spinal injuries and disabilities largely depends on the early start and correct selection of rehabilitation programs. In addition, the choice of methods and means of physical rehabilitation and physical activity for people with disabilities in the limited military and emergency conditions depends on their general physical and mental condition, the presence of accompanying diseases and complications, as well as on the surrounding circumstances. However, regardless of the difficulties and surrounding circumstances, people with disabilities (in a wheelchair) or with an injury and spine diseases must be engaged in physical therapy and do physical exercises in order not to lose the physical capacity for action, even limited, to be able to adapt to the circumstances and mobilize functional reserves of their bodies. Conclusion. Comprehensive rehabilitation is an integral part of therapy for patients with spinal injuries, people with disabilities (in wheelchairs), etc. Physical exercises not only affect the development of the motor activity of people with disabilities but also increase the body's resistance to adverse environmental factors, activating vegetative systems, stimulating and normalizing functions of body systems. The gradual adaptation of the body to physical exertion leads to adaptation, mobilization and use of the body's functional reserves. Physical training itself is an adaptation process that activates the body's hidden reserves

Sustaining the Integration of Technology Pedagogies in Higher Education after the COVID-19 Pandemic
Authors: Bhebhe Sithulisiwe
Published: February 2023

This study sought to determine the support provided to lecturers from selected universities in Southern Africa in sustaining the integration of technology pedagogies to train in-service teachers after the COVID-19 pandemic era. The study used a multiple case study design and a qualitative research approach as part of an interpretive research paradigm. The study was carried out at two Southern African universities that were conveniently chosen by the researchers as their places of work. A purposive sample of lecturers in the faculties of education that train in-service teachers was selected. Data were gathered through the analysis of documents considered relevant to the study from the studied universities. A focus group discussion was held with 12 lecturers, an open-ended questionnaire was completed by 9 lecturers and open-ended interviews with 6 HODs in the faculties of education were conducted. Data obtained from the participants and the documents examined were analysed using thematic analysis. The study's findings reveal that lecturers from both universities initially had limited knowledge as they were still transforming from face-to-face teaching pedagogies and needed to be knowledgeable about integrating technological pedagogies in training in-service teachers. Findings also show that the universities provided some internet connectivity for lecturers to use especially when they were on campus, but internet access was limited when they moved off campus premises. Institution A failed to give lecturers data for off campus usage, while institution B gave lecturers data for off campus usage, but load-shedding (regulated power outages) took a toll in the country where institution B is situated. The study concludes that lecturers received support from the universities where they work to enable appropriate technology pedagogy integration in the preparation of in-service teachers.

Published: February 2023

Purpose: The article presents a set of indicators for assessing the effectiveness of an energy management system (EnMS) based on the authors’ own research findings. Design/methodology/approach: The work uses qualitative methods such as systematic review of literature, analysis of the content of existing documentation, participatory observation and self-observation. Findings: The literature on the subject features few publications dedicated specifically to energy management systems. Moreover, no practical solutions with a set of practical metrics to be applied in the regular process of realising energy programs and goals exist. Hence, the authors propose a model of assessment. Practical implications: The set of indicators presented in the article offers good practical value and high application and adaptation potential. The model may be applied in individual businesses in the chemical sector or as a benchmarking tool in capital groups or a group of entities demonstrating functional connections. Consisting of the universal part (indicators for goals and processes) and the sector-relevant indicators, the model may be adapted for use in other sectors through appropriate corrections for the sector-relevant criteria. Originality/value: The assessment model presented in the article fills a publication void and represents an innovation. It is intended for use in managing and supervising energy-related activities in various organisations. It shall prove of assistance to system users and auditors alike.

Published: February 2023

Purpose: Our attention was directed to high-growth enterprises (HGEs) whose development is associated with an accelerated cycle of growth and value creation that is a result of the scalability of their business models. The primary research objective of the article is to analyze the value components in the business models of high-growth enterprises divided into three size groups (small, medium, large). We pose the research question: which components build value in HGE enterprises' business models under uncertainty? Design/methodology/approach: An empirical study for HGEs was conducted after the third wave of the pandemic in October 2021 using a survey questionnaire on the sample consisted of a total of 125 Polish companies. The relationships between variables were analyzed using structural equation modelling (SEM) based on the maximum likelihood method. Empirical research in relation to theoretical constructs in business models divided into three size groups of businesses allowed us to notice that only in the case of small enterprises, the creation and delivery of value affect the value proposition. Findings: Empirical research in relation to theoretical constructs in business models divided into three size groups of businesses allowed us to notice that only in the case of small enterprises, the creation and delivery of value affect the value proposition. Exploration of business models of high-growth companies allows for a conclusion that building value in conditions of uncertainty should be based on stable foundations, which are regular customers and key customers, as well as well-proven products/services created under license. Originality/value: The novelty of the paper are conducted researches on business models of HGEs during pandemic Covid-19.

Published: February 2023

Purpose: To determine how remote education at Polish universities of economics changed between the first and second term of classes held during the pandemic (March-June 2020 vs. October 2020-February 2021). Design/methodology/approach: The paper is based on a survey of organisational changes implemented by four Polish universities of economics (in Katowice, Kraków, Poznań, and Wrocław) as a result of the Covid-19 outbreak. Findings: It was found that in the winter term 2020/21, the timeliness of educational activities noticeably improved and synchronous methods were employed more frequently, whereas email was the preferred mode of communication for tutorials in both terms. Social implications: The universities surveyed were able to respond to the crisis within a reasonably short time and continued to provide education throughout the pandemic. The findings imply that the interruption of face-to-face instruction should have little effect on their students’ employment prospects after graduation. Originality/value: The case study looks in depth at the process of organisational change forced by external circumstances at four organisations. It also illustrates the direction and magnitude of adjustments made by the selected HEIs as perceived by their students. To date, no comparable research on the subject has been published in the literature. Funding: The publication was financed from the subsidy granted to the Cracow University of Economic – Project nr 046/GAP/2022/POT.

Published: February 2023

Purpose: Digital transformation affects all spheres enterprises operate in regardless of their size and industry. Its impact is analyzed by the representatives of various sciences and business practitioners as well as. The objective of the article is to present theoretical and empirical research on the digital activity of Polish small enterprises. Design/methodology/approach: Two methods were used to achieve the objective. The method of literature review consisted in the analysis of literature in the field of digitalization and digital transformation. It gave the foundation for the development of methodological assumptions. The diagnostic poll method with the use of the survey technique was employed to conduct the empirical study among Polish small enterprises. The results of the research allowed the organizations’ activity to be assessed. Findings: The study indicated that the digital activity of Polish small enterprises is not satisfactory. Their innovation is low, investment in ICT is sporadic and insufficient. Predominantly, the enterprises implement ICT solutions which do not require expert digital competences. The surveyed companies recognize the benefits of digitalization and its significant impact on opportunities for development. Digitalization is hampered by fears of incurring high costs, necessity of employing IT specialists or supplementing digital competences of the management and employees. Research limitations/implications: The present study examined the issue of digital activity of small enterprises and enabled the adopted research assumptions to be verified. Prospective research may analyze the digital activity of the surveyed enterprises in terms of age, size and industry groups. Practical implications: The research allowed practical problems of digitalization of small businesses to be identified. A consecutive round of the study conducted in the following year would be worthwhile in order to analyze the dynamics of digital transformation in this sector. Originality/value: The originality of the research consists in introducing the concept of digital activity of enterprises and its assessment exclusively in relation to small enterprises, which are the weakest link in the SME sector. Keywords: small enterprises, digital activity, digital transformation. Category of the paper: Research paper.

Purpose: Identification and assessment of the impact of human capital on the effectiveness of enterprises of the Visegrad Group (V4). Design/methodology/approach: In the theoretical part, content analysis was used - a library query on the Google Scholar website. In the empirical part, a statistical analysis was applied, which included the characteristics of the sample of selected features, the analysis of a series of correlations examining the matching of features, and the analysis of the results obtained. The collected data was compiled using descriptive statistics - average values, dynamics of changes, trend function and Pearson's correlation coefficient. Findings: In each V4 country, as the turnover of enterprises increased, the number of unemployed people with higher education decreased, and vice versa. The increase in the turnover of enterprises determined the increase in the number of research and development personnel in each country of the Visegrad Group (and vice versa). In turn, the turnover of V4 enterprises turned out to be strongly correlated with labor costs. Along with the decrease in the number of research and development personnel, as well as labor costs, the gross operating index of companies from the Visegrad Group increased. Practical implications: It was attempted to show which of the examined attributes of human capital had the greatest impact on the effectiveness of enterprises in individual V4 countries. This gives a certain field, on the one hand, to combat unemployment by applying a targeted state policy aimed at reducing its level, and on the other hand, to introduce incentives promoting the employment of R&D personnel. Limitations: Short time series containing the attributes of human capital and enterprise efficiency, as well as the lack of current and complete statistical data, which resulted in a reduced number of predictors tested. Keywords: human capital, enterprise efficiency, Visegrad Group. Category of the paper: Research paper.
