Degree of Stability of the Reputational Core of the Russian Power: Substantiation of Choice Patterns in Public Opinion
Authors:   Smolensk State University, Rozanova Nina N.
Published: February 2024

The article presents the results of the study of the reputation of the Russian power to identify the degree of strength/stability of links between the content characteristics of reputation, using the example of the opinion of residents of two subjects of the Russian Federation – the city of Moscow and the Republic of Komi. In the con-tent of the reputation core, the characteristics that are relatively stable due to their sharing by the majority, and less significant and more mobile characteristics are identified. To solve the problem of substantiating the posi-tion on the degree of stability or dynamism of reputation characteristics, the processing of respondents’ an-swers was carried out using NetworkX and Matplotlib libraries of the Python programming language. A funda-mental conclusion was obtained that there is the greatest strength and, accordingly, stability of the links be-tween the priority reputational characteristics of the Russian public power and further, in descending order, the increase in their dynamism. This conclusion also applies to the reputation of the regional executive power.

Recently, many scholars have been drawn to the use of gamification in education to promote learners’ engagement and improve their learning outcomes. Gamification is regarded as a novel technology-based teaching and learning tool that promotes learning in a fun and engaging manner. Using the modified technology acceptance model (TAM) as its theoretical foundation, the present study is designed to investigate the students' acceptance of the use of gamification to support their mathematical learning during open and distance learning (ODL). Free online gamification tools were designed for a mathematics course, namely, Further Differential Equations. A sample of 49 civil engineering degree students was selected to participate in this study for using gamification tools. The primary research methodology applied in this study was a quantitative approach based on a modified TAM survey questionnaire. The questionnaire results were analysed using descriptive statistics, independent samples t-test and correlation analysis. The analysis was focused on four proposed determinants, namely perceived usefulness, perceived ease of use, attitude towards using, and behaviour for intention to use. Findings revealed no statistical differences between male and female groups on all four determinants proposed in modified TAM's model. Also, the study discovered significant positive relationships among all of the model's determinants on gamification acceptance.

Authors: Kim Kihwan , Adams-Harmon Dawn
Published: February 2024

The literature on college attrition rates has revealed that self-efficacy and locus of control play a critical role in academic performance and retention. However, despite the importance of students’ attitudes in academic performance, there have been few studies focused on how to develop students’ self-efficacy and internal locus of control. We examined the impact of motivational book reading on the promotion of self-efficacy and locus of control by leveraging a mixed method study, analyzing quantitative and qualitative data. One hundred diverse, business students participated in the research, where they read one motivational book and wrote essays to reflect their learning and took surveys that measured the quantitative variables before and after reading the book. The analysis revealed that motivational book reading significantly increased self-efficacy and locus of control of the participants. The qualitative analysis revealed that students expressed improvement in self-efficacy and internal locus of control after reading the book. The limitations, practical implications, and future research implications are discussed in this paper.

Authors: Yusuf Wibisono  , Heru Susetyo Nuswanto
Published: February 2024

The rising incidence of rape has captured public attention, presenting challenges in investigation, prosecution, and verdicts. Rape is defined as a violent act or threat of violence to coerce non-consensual sex with a woman, not one's spouse, exemplified in Decision Number 390/Pid.B/2021/PN Smn. This research delves into the theoretical and regulatory aspects of rape in Indonesia, particularly the application of Article 285 of the Criminal Code to helpless victims, posing questions about its appropriateness. Utilizing a normative approach with descriptive analysis, secondary data was collected through a literature review. The research concluded that the perpetrator's actions constitute 'exploitation rape,' and the victim qualifies as a 'pure victim' with no prior association with the offender. Furthermore, the perpetrator's actions more closely align with the elements of Article 286 of the Criminal Code.

295 children’s bronchoscopy due to choking episode with suspected foreign body in the of pediatric ent department – analysis of choking risk factors
Authors: Jabłońska-Jesionowska Monika , Zawadzka-Głos Lidia
Published: February 2024

Introduction. Aspiration of foreign body by children is a common cause of respiratory failure and an indication for urgent bronchoscopy. This procedure under general anesthesia is very difficult, stressful and dangerous in children due to their small diameter of the respiratory tract with a symptom of dyspnea. The tendency to put everything in to the mouth for cognitive purposes, incomplete dentition, immature swallowing mechanism are all the factors of high risk of choking episodes in very young children. Over the years still has been discussions on how to limit the number of bronchoscopies performed in children. Aim.The authors of this analysis try to find an answer to the question of whether and which way the number of bronchoscopy of the lower respiratory tract in children can be limited. Material and methods. 295 children underwent a bronchoscopy in the Department of Pediatric Otolaryngology of the Medical University of Warsaw in 2015-2020 after an episode of choking with suspected foreign body of the lower respiratory tract. The procedure was done after an appropriate pediatric examination and X-ray of the chest. In the analysis, particular attention was paid to the type of foreign bodies, pathology in clinical examination and tests. Results. 295 patients underwent rigid bronchoscopy under general anestesia. The indications for this procedure was single episode of choking. All children presented some patology in physical examination or on chest X-ray. Only in 142 (48%) patients a various foreign bodies were found and removed. That were 110 (77.5%) organic and 32 (22.5%) inorganic foreign bodies. Among all 142 cases only 9 (6%) were visible on X-ray. Peanuts and seeds were the most common foreign bodies, identified in 81% patients. The median age was 2 years. Conclusions. There are not characteristic symptoms of foreign body in respiratory tract in clinical investigation after single episode of choking. The suspicion of aspiration is still the main indicates for urgent bronchoscopy in children. It seems that the number of performed bronchoscopies could be reduced by prevention. Extensive education for young parents should be providing to inform them about choking hazard. We should pay special attention to them not to give small hard organic food to their children; especially nuts and grains. Parents’ attention should also be paid to toys, which for toddlers must be free of small, moving parts. Also companies producing food and toys for children should be obliged to place information on the risk of chocking on their products.
Diagnosis and treatment of Schwannoma of the parapharyngeal space on the example of a 14-year-old male patient

Published: February 2024

The parapharyngeal space is located on the side of the pharynx wall. It is an inverted pyramid-shaped anatomical area filled with adipose and connective tissue. Schwannoma (neurinoma) is a benign tumour that originates from the Schwann cells that form the myelin sheaths of nerves. This neoplasm in the parapharyngeal space usually arises from the vagus nerve and the sympathetic trunk. Parapharyngeal space tumours are often a complicated diagnostic and therapeutic problem. A 14-year-old patient was admitted to the hospital because of a feeling of discomfort in the throat due to a nodular lesion on the right side. The lesion was removed through transoral approach. The patient remains under laryngological and oncological care. In follow-up examinations 6 months and 1 year after surgery, no features of recurrence were revealed. Due to their rare occurrence, non-specific symptoms, and anatomical topography, the diagnostic and therapeutic process of parapharyngeal space tumours is very difficult.
URBAN AND SUBURBAN LAND FRAGMENTATION IN NORTHEASTERN POLAND
Authors: Strzyż Małgorzata , Łapińska Halina , Szewczyk Jarosław
Published: February 2024

The authors prove that relic land fragmentation can be a valuable component of urban and suburban landscape as a remnant of its history and a testimony to the past economic and social phenomena, as shown in the case study of the City of Białystok and the Town of Łapy, located in northeastern Poland. Such relics deserve to be considered in spatial planning, inducing both problems and new opportunities. Accordingly, the relevant discussion focuses on two examples of places where land fragmentation reached unprecedented proportions, especially in the 1920s. The most extreme historic examples are described, such as a farm divided into 1,221 plots in Łapy (52°59´28˝N, 22°53´07˝E), mentioned in 1926. Based on the most recent cadastral maps (2020), the contemporary remnants of extreme land fragmentation in Białystok and its land district (approx. 52°51´00.8˝-53°23´02.4˝N; 22°28´09.1˝-23°56´45.4˝E) are assessed. Distribution of landscapes with prevailing plots narrower than 30 m and with plots narrower than 15 m is mapped. The results of the study are discussed against the background of broader historical and geographic context, in order to evaluate such “fossil landscapes” as a valuable cultural component. Recommendations are also formulated on the protection of relics of land fragmentation. In particular, the structure of their baulks should be locally restored to make highly fragmented arable lands discernible. The results of the study can contribute to discussions on the protection of fragmented land in other countries, especially in Eastern Europe, where the land fragmentation (‘checkerboard’) came into existence and perpetuated as a result of both settlement patterns and subsequent economic and social processes. However, compared to other urban areas, including those in neighboring countries, land fragmentation in Białystok is of a scale unknown elsewhere and deserves special attention from a conservation and heritage perspective.
The Effect of NaOH Concentration and Acetylation Time on Synthesis of Kepok Banana Peel Cellulose Acetate
Authors: Yasmin Fia Kharisma , Pramita Ayu , Satriawan Dodi
Published: February 2024

The high production of kepok banana is generating a significant amount of peel waste, contributing to environmental pollution. To address this issue, an innovative solution is the conversion of kepok banana peel into cellulose acetate as raw material for membrane production. Therefore, this research aimed to manufacture kepok banana peel cellulose acetate using varying concentrations of 1%, 1.5%, and 2% NaOH solvent, with acetylation times of 2 hours and 2.5 hours, respectively. The optimal results were achieved using 1% NaOH with kepok banana peel cellulose content of 56.07%. Furthermore, the best acetylation time occurred at a duration of 2.5 hours, producing a cellulose acetate content of 38.23% and a 2.3% degree of substitution (DS). These results suggested that the optimal combination for producing membrane from kepok banana peel is 1% concentration with an acetylation time of 2.5 hours, classifying it as cellulose diacetate.
A unified charge storage mechanism to rationalize the electrochemical behavior of quinone-based organic electrodes in aqueous rechargeable batteries
Authors: WANG Wenkang , BALLAND Véronique , BRANCA Mathieu , LIMOGES Benoît
Published: February 2024

Due to their eco-sustainability and versatility, organic electrodes are promising candidates for large-scale energy storage in rechargeable aqueous batteries. This is notably the case of aqueous hybrid batteries that pair the low voltage of a zinc anode with the high voltage of a quinone-based (or analogue of quinone-based) organic cathode. However, the mechanisms governing their charge-discharge cycles remain poorly understood and are even a matter of debate and controversy. No consensus exists on the charge carrier in mild aqueous electrolytes, especially those containing a multivalent metal cation such as Zn2+. In this study, we comprehensively investigate the electrochemical reactivity of two model quinones, chloranil and duroquinone, both when diluted in solution or incorporated into carbon-based composite electrodes. We demonstrate that a common nine-member square scheme proton-coupled electron transfer mechanism can fully describe and rationalize their electrochemical behavior in relation to pH and chemical composition of the aqueous electrolyte. Additionally, we emphasize the crucial role played by the pKas associated with the reduced states of quinones in determining the charge carrier involved in compensating negative charges reversibly injected in the active material. Finally, contrary to widely reported findings for Zn/organic batteries, we unequivocally establish that the predominant solid-state charge carriers in Zn2+-based mild aqueous electrolytes are not multivalent Zn2+ cations but rather protons supplied by the weakly acidic hexaaqua metal ions (i.e., [Zn(H2O)6]2+]).
Identification of reaction network hypotheses for complex feedstocks from spectroscopic measurements with minimal human intervention
Authors: Srinivasan Karthik , Puliyanda Anjana , Prasad Vinay
Published: February 2024

In this work we detail an automated reaction network hypothesis generation protocol for processes involving complex feedstocks where information about the species and reactions involved is unknown. Our methodology is process agnostic and can be utilized in any reactive process with spectroscopic measurements that provide information on the evolution of the components in the mixture. We decompose the mixture spectra to obtain spectroscopic signatures of the individual components and use a 1-d convolutional neural network to automatically identify functional groups indicated by them. We employ atom-atom mapping to automatically recover reaction rules that are applied on candidate molecules identified from chemistry databases through fingerprint similarity. The method is tested on synthetic data and on spectroscopic measurements of lab-scale batch Hydrothermal Liquefaction (HTL) of biomass to determine the accuracy of prediction across datasets of varying complexities . Our methodology is able to identify reaction network hypotheses containing reaction networks close to the ground truth in the case of synthetic data and we are also able to recover candidate molecules and reaction networks close to the ones reported in previous literature studies for biomass pyrolysis.

Advances in liquid phase transmission electron microscopy (LP-TEM) have enabled the monitoring of polymer dynamics in solution at the nanoscale, but radiolytic damage during LP-TEM imaging challenges its routine use in polymer science. Here, we focus on understanding, mimicking and mitigating radiolytic damage observed in functional polymers in LP-TEM. Using polymer vesicles in aqueous solutions as a model system, we quantitatively show how polymer damage occurs in all conceivable (LP-)TEM environments to which polymers might be exposed. It is found that radiolytic damage to polymers is negligible in vacuum but becomes substantial in water-containing environments. We elucidate the primary characteristics of polymer damage in water vapor and liquid water, addressing the observed differences. Furthermore, we introduce ultraviolet light irradiation in the presence of hydrogen peroxide to replicate the observed polymer damage and morphological changes on lab scale, allowing the use of bulk techniques to probe damage at the polymer chain level. Finally, we compare the protective effects of commonly used hydroxyl radical scavengers and reveal that the effectiveness of graphene's protection is distance dependent. We anticipate that our work will help to guide the design of LP-TEM experiments for polymers in a rational and informed manner.
Structural reconstruction of cobalt and ferrocene-based metal-organic framework during electrochemical oxygen evolution reaction
Authors: Doughty Thomas , Zingl Andrea , Wünschek Maximilian , Pichler Christian , Watkins Matthew B. , Roy Souvik
Published: February 2024

Metal-organic frameworks (MOFs) are increasingly being investigated as electrocatalysts for oxygen evolution reaction (OER) due to their unique modular structures that present a hybrid between molecular and heterogeneous catalysts, featuring well-defined active sites. However, many fundamental questions remain open regarding the electrochemical stability of MOFs, structural reconstruction of coordination sites, and the role of in situ-formed species. Here we report structural transformation of a surface-grown MOF containing cobalt nodes and 1,1’-ferrocenedicarboxylic acid linkers (denoted as CoFc-MOF) during OER in alkaline electrolyte. Ex situ and in situ investigations of CoFc-MOF film suggests that the MOF acts as a pre-catalyst and undergoes a two-step restructuring process under operating conditions to generate a metal oxyhydroxide phase. The MOF-derived metal oxyhydroxide catalyst, supported on nickel foam electrodes, displays high activity towards OER with an overpotential of 190 mV at a current density of 10 mA cm–2. While this study demonstrates the necessity of investigating structural evolution of MOFs in electrocatalysis, it also shows potential of using MOFs as precursors in catalyst design.
