Discourse on Peace and Balance of Power in Early Eighteenth-Century English Political Sermons
Authors: Schvéd Brigitta
Published: November 2023

In the public debate on the English involvement in the War of the Spanish Succession, and over time, on the peace that would end the prolonged war, sermons occupy a special place among the various political mediums of the time. After briefly reviewing the main features of the political controversy, the present study specifically examines two political sermons by the English churchman John Adams (1662–1720), in which the discourse on balance of power is organically present, reinforcing the theme of the need for a “good peace”. In Adams’ sermons, published in 1709 and 1711, respectively, the notion of Christian joy and prosperity as well as the glad tidings of the securing of Protestant succession in the form of a future peace were given explicit emphasis alongside the discourse on balance of power. Both sermons were delivered on thanksgiving days, therefore – while supporting the anti-war, pro-peace Tory propaganda – they have a strong emphasis on predictions of the positive prospects for Christian spirituality. The paper focuses on the conceptual analysis of these delightful promises, showing how Adams considered the effects of a prospective peace on the Christian religion in general as well as on the future of the balance of power both at home and in Europe.
Displays of Statehood
Authors: Gueudet Sophie
Published: November 2023

Drawing on a qualitative analysis of primary sources and interviews with members of representative offices, this article shows how five post-Soviet de facto states—Transnistria, South Ossetia, Abkhazia, the so-called Donetsk People’s Republic (“DPR”), and Luhansk People’s Republic (“LPR”)—engage in activities of international representation by borrowing from diverse repertoires of diplomatic practices, generating hybrid practices of their own. On the one hand, they are attentive to looking like bona fide states and to displaying material and symbolic attributes of statehood through mimicking state-led diplomacy. On the other, they resort to creativity and innovation to partially compensate for the constraints intrinsic to their ambivalent status and complete their repertoire with practices similar to those of transnational advocacy networks, especially regarding information politics and public diplomacy. Overall, the article aims to contribute to the field of contested statehood, as well as to the study of the international engagement of non-state actors in situations of liminality in the international system.

Published: November 2023

Few studies have focused on reclassifying follicular adenomas (FAs) as noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTPs), but none have been conducted in America or Europe. The aims of this study were to analyze the prevalence of NIFTP reclassified from follicular variant of papillary thyroid carcinomas (FVPTCs) and FAs before NIFTP was defined in the literature, the rate of NIFTP among PTC (papillary thyroid carcinomas) established in real time between 2017 and 2022, and demographic, ultrasonographic, and cytologic characteristics of NIFTPs compared with FVPTCs and FAs. This was a retrospective cohort study of tumors diagnosed as PTCs (n = 247) and FAs (n = 144) at a Brazilian hospital. Overall, 13.4% of PTCs and 7% of FAs were reclassified as NIFTPs. The rate of real-time diagnosed NIFTPs among PTC was 12.3%. The median tumor size was larger among NIFTPs (3.0 cm) than FVPTCs (1.1 cm; P < 0.01). A high-risk ultrasonographic pattern was rare in NIFTPs (5.6%). The cytologic classifications differed between FVPTCs and NIFTPs (P < 0.01), and the most frequent category among NIFTPs was ‘follicular neoplasm’ (52.6%). The category ‘suspicious for malignancy’ was frequent in FVPTCs and rare (5.3%) in NIFTPs. In conclusion, FVPTCs and FAs may be reclassified as NIFTPs. The prevalence of NIFTPs reclassified from FAs was lower in our cohort than in Asian studies. The rate of NIFTPs reclassified from PTC was similar to that of NIFTPs diagnosed in real time and was aligned with rates reported in studies from America and Europe. Preoperative features could not differentiate NIFTPs from FVPTCs or FAs.

INNOVATIVE APPROACHES TO THE USE OF FEEDBACK TECHNIQUES IN THE EDUCATIONAL PROCESS OF HIGHER EDUCATION INSTITUTIONS
Authors: Chervinska Inna , Vasylyk Maryna , Neyko Nila , Chervinskyi Andrii
Published: November 2023

The authors formulate the essence of feedback, describe the organisational and didactic conditions for its effective provision in the educational process of a higher education institution. The authors propose to consider feedback in two aspects: as an option for establishing successful communication and interaction between the teacher and the higher education applicant, and as an option for effective feedback for assessing academic achievements and controlling the knowledge of higher education applicants. The article emphasises the recognition of the importance of the correct application of feedback techniques in the educational process, since it can have both a positive and a negative impact on the organisation of the educational process and the success of higher education applicants. The blended learning format, unlike other modern forms of organising the educational process, involves the use of remote access mode, which usually makes it impossible to communicate and interact directly between the teacher and the education applicants. It is noted that feedback should be considered in the context of the educational component where it is applied. The researchers note that feedback is a means of obtaining important information, the results of educational activities necessary for the effective management of the educational process in a blended learning format. It is noted that the purpose and main objectives of the study are to reveal innovative approaches and organisational and didactic conditions for the use of feedback techniques in the educational process of a higher education institution. The authors point out that innovative ideas of feedback techniques are successfully implemented in the modern educational space of Ukraine. It is emphasised that the effectiveness of implementing feedback techniques in higher education institutions depends on the context, goals, objectives and content context of education and upbringing of a growing personality. The concept of feedback is considered by many sciences within the framework of different scientific approaches and directions, since it mostly has a different interpretation and meaning, as it is one of the main elements of the functioning of the educational system.
Islamic banks' commitment to Sharia controls (Murabaha contracts, Ijarah contracts) Status (Banks working in Jordan)
Authors: Al-Taani Attallah Hassan Mohamed
Published: November 2023

This study focused on Islamic banks' adherence to Sharia controls when executing contracts, and the focus was on the most common debt contracts, which are contracts that all banks (Islamic and conventional banks) compete for. What distinguishes Islamic banks from traditional ones is the commitment to Sharia controls in Islamic banks. The most important results were that the motive for dealing with Islamic banks is religious motive, and that Islamic banks adhere to Sharia controls when drafting contracts, but their employees do not adhere to these controls when executing contracts. Islamic banks focus their investment efforts on debt contracts and on the youth category with fixed incomes, least riskiness, and not to focus on other Islamic contracts (Mudarabah, Musharaka, ...) that are riskier. There is no relationship between the type of contract and the extent of compliance with Sharia controls when executing contracts in Islamic banks.
Más allá del verso y la prosa: la pugna estilística en Escalas (1923) de César Vallejo
Authors: Avalos Salas Eduardo Mijaíl , Arcila Medina Daniela
Published: November 2023

Para la crítica, Escalas (1923) forma parte de las creaciones menores de César Vallejo, en tanto que ha sido considerado un bosquejo que permite la explicación de otros textos de la producción poética y narrativa del vate santiaguino. Por esta razón, en homenaje a su centenario, este artí- culo tiene como propósito ofrecer una nueva lectura de Escalas a la luz de los aportes de la Retórica General Textual. Para ello, se plantea como hipótesis que el carácter hermético de Escalas no es producto de la inexperiencia de Vallejo como narrador, sino de su conciencia experimental. Esta tiene su correlato en una pugna estilística entre tres regímenes de pensamiento: el separativo, el distintivo y el confusivo. Se emplea como marco teórico principal la clasificación de Giovanni Bottiroli sobre los estilos de pensamiento, además de las categorías de campo retórico y campo figurativo propuestas por Stefano Arduini.

La visibilización de un material simbólico como el literario siempre supone un reordenamiento del campo artístico y cultural. El rescate literario, por su parte, además de involucrar lo anterior, se comporta como un terreno fértil que permite la proyección de continuidades y tensiones, de ideas y afectos; en suma, de un mosaico de voces que han estado vibrando en un espacio encriptado durante mucho tiempo. En ese sentido, tras un arduo trabajo, se ha conseguido una valiosa publicación: Chirapu. Edición facsimilar (2021), editado por Luis Apaza Calizaya con el apoyo de la Universidad Ricardo Palma de Lima; dicho libro se compone de dos bloques: por un lado, cinco textos redactados, respectivamente, por Iván Rodríguez Chávez, Luis Apaza Calizaya, Ayar Peralta Vizcarra, Mauro Mamani Macedo y Alex Hurtado Lazo, y, por otro lado, los siete números de Chirapu (1928).

Authors: Paliulytė Milda , Šustickas Gytis
Published: November 2023

Objectives. To assess characteristic data of patients hospitalized due to subacute subdural hematomas (SSDHs) and chronic subdural hematomas (CSDHs) and to evaluate radiological findings and establish predictors of hematoma recurrence of SSDHs and CSDHs patient populations. Methods. 149 patients with SSDHs and CSDHs who underwent surgery at Kaunas Clinics Neurosurgery Department from 2020 to 2021 were analyzed. Based on recurrence rate, patients were divided into different subtypes based on computer tomography (CT) imaging. Descriptive analysis, hypothesis testing and correlation matrix were performed using Excel spreadsheet and R programming language with the significance at p-value < 0.05. Results. Out of 149 patients, SSDHs and CSDHs were observed in 89 males (59.6%) and 60 (40.3%) females. Mean of the patients age was 71.1±15 years. Dichotomizing results based on recurrence (cut-off value of 25%), 2 groups were made: 1) low reoperation rate –hypodense sedimented (10%), isodense (21.6%), hypodense (22.2%); 2) high reoperation rate – hypodense bridging (26.7%), hypodense trabecular (27.8%), hypodense with acute bleeding (28.6%), hypodense laminar (30%), isodense with acute bleeding (33.3%). Conclusion. It is concluded that based on 25% reoperation rate high-recurrence and low-recurrence chronic subdural hematomas groups were similar in all terms apart from the hematoma thickness (mm), which leads to a fact that radiological appearance of higher recurrence hematomas should be carefully taken into consideration.

Authors:   National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”, Malykhina Yuliana , Chyhyrynets Olena ,   National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”
Published: November 2023

This study aimed to synthesize and characterize inclusion complexes of ferulic acid incorporation based on modified β-cyclodextrin (MCD). Ferulic acid (FA), a natural antioxidant with limited water solubility, is challenging to deliver effectively to the human body. Therefore, to konoenhance its stability and solubility, it was encapsulated in cyclodextrin with a modified surface. The interaction between ferulic acid and the modified β-cyclodextrin compound was confirmed through Fourier transform infrared spectrometry (FT-IR). The thermogravimetric analysis (TGA) indicated that the successful encapsulation of ferulic acid in the β-cyclodextrin cavity led to increased thermal stability of the FA-MCD inclusion complex compared to the individual components. These findings suggest that the modified β-cyclodextrin can serve as a promising carrier for improving the delivery and effectiveness of ferulic acid as an antioxidant in various pharmaceutical applications.

The strength of pearlite rail steels has reached its limit. An increase in the carbon content will affect the impact strength and weldability of rail materials. Thus, there is a need for other alternative materials. The use of bainite steel, which provides both high strength and excellent plasticity, is considered one of the most promising areas. As a result, recommendations were presented regarding the chemical composition for further production of experimental ingots. From the results of the microstructure analysis, it was established that test steel No. 1 has a pearlite structure with areas of coarse-plate pearlite and austenite along the grain boundaries, test steel No. 2-4 mainly has a structure of granular bainite and residual austenite.

The objective is to demonstrate a new fuel electrode solution for the innovative Molten Carbonate Electrolysis. The innovative material is a Ru-supported fuel electrode for Molten Carbonate Electrolysis, which aims to enhance the catalytic property of the standard fuel electrode and accelerate the reactions associated with the production of synthetic fuel. Molten Carbonate Electrolysis is a technology capable of converting a mixture of water and carbon dioxide into hydrogen, carbon monoxide, and various hydrocarbons in a single step using the co-electrolysis principle. This technology’s advantage over other electrolyzers is its ability to produce fuel with a high energy density that contains hydrocarbons. The addition of a catalyst to a new fuel electrode is intended to accelerate the hydrocarbon conversion reaction, thereby enhancing the final fuel mixture. In this project, it is envisioned that a prototype of a new electrode will be manufactured with Ru proportions of 5%, 10%, and 15% in standard Ni-based slurry. The performance enhancement of the new electrodes for Molten Carbonate Electrolysis will be investigated by testing them in the lab. At the conclusion of the project, the prototype with the best performance will be prepared as the demonstrator and selected for future research.

Published: November 2023

A numerical method of evaluation of the period of initiation of a fatigue microcrack at the tip of a surface cavity-like defect in the wheelset axle of a railway car is proposed. In this method, we use a model based on the energy approach of fracture mechanics. It is shown that if the surface cavity-like defect is located in the most loaded place of the axle, then a fatigue microcrack can be initiated near its smooth tip for a relatively short period of operation of the axle.

Authors:   Karpenko Physico-Mechanical Institute of NAS of Ukraine, Sharabura Oleksiy
Published: November 2023

The solution of the wave diffraction problem that is obtained in [1] is modified and applied for modelling of the axially symmetric transverse magnetic (TM) waves scattering from the conical probe in the presence of half-spherical defect on the plane surface. This structure is modelled by a bicone with semi-infinite and truncated semi-infinite perfectly conducting conical shoulders and the spherical diaph­ragm. The structure is excited by the radial electric dipole. The mode-matching and analytical regularization techniques are used for the solution of the problem. Based on the obtained solution, the near and the far fields scattered from the defect are analysed for determining the information parameters for its identification.

OBJECTIVE

Communication skills are critical to pediatric practice, but few pediatric residency programs provide formal communication skills education. Pediatric residents often lack confidence in these skills. We hypothesized that a simulation-based communication skills course would improve resident confidence in the skills required for serious illness conversations with patients/families.

METHODS

In collaboration with multidiscipline VitalTalk-trained faculty, we developed PedsTalk, a communication skills course for pediatric residents based on the VitalTalk framework. In PedsTalk, faculty/peers offered real-time coaching during simulation sessions with actors. Resident participants self-rated confidence in 9 communication skills using a 5-point Likert scale before, immediately after, and 4 months after course participation, with course nonparticipants serving as controls. Responses were analyzed by using Friedman tests and Wilcoxon rank tests. Thematic analysis was conducted to identify themes among free-text responses.

RESULTS

Twenty-seven pediatric residents participated in PedsTalk, 11 of whom completed survey assessments at all timepoints. Eleven course nonparticipants served as controls. Over time, participants’ confidence in the following communication skills was retained or significantly improved: “difficult conversations” (P < .001), “recognizing emotion” (P < .01), “using silence” (P < .008), “headline statements” (P < .001), eliciting “VALUES” (P < .001), and asking “permission to continue” (P < .001). Over time, controls had significant improvements in confidence in 2 skills: headline statements (P < .014) and eliciting “VALUES” (P < .031).

CONCLUSIONS

PedsTalk is a novel approach to communication skills education in pediatric residency. Participation improved residents’ confidence in 6 communication skills, including overall confidence in having difficult conversations. Although confidence in some skills may naturally develop through clinical experiences, PedsTalk further enhances communication skills education among trainees.

We report the case of a male patient who had a history of early-onset protein-losing enteropathy, chronic diarrhea, and repeated thrombotic events since early childhood. He developed Budd-Chiari syndrome with consequent acute liver failure that required liver transplantation when he was 12 years old. The initial graft failed to function and he required retransplantation. Steroid-resistant rejection complicated the clinical course after the second transplant. Treatment with antithymocyte globulin stabilized graft function but abdominal symptoms and enteral protein loss persisted. The patient remained dependent on intravenous albumin and immunoglobulin.

Extended work-up for thrombophilia was unremarkable. Flow cytometry analysis of the peripheral blood cells revealed an unexplained CD55 deficiency. By sequencing of CD55 and, later, exclusion of alternative rare diseases by whole-exome sequencing, we discovered a novel, likely pathogenic homozygous splice-site variant in CD55 c.578 + 5G>A, NM_000574.4, OMIM 125240. The staining of liver and colon biopsies revealed a lack of CD55 protein expression.

After initiation of treatment with eculizumab, the patient achieved and has maintained a complete clinical remission throughout 56 months of follow-up. We recommend testing for CD55 deficiency in patients with protein-losing enteropathy. In addition, CD55 deficiency should be considered in the differential diagnosis of patients with Budd-Chiari syndrome in whom an underlying cause is uncertain.
The curious case of the lion from Berlin in summer’ 23: how Internet media shapes risk perception from wildlife-human conflict
Authors: Oelke Jordan , Jarynowski Andrzej , Belik Vitaly
Published: November 2023

Introduction. This paper explores the reactions of citizens to a perceived security risk at the human-wildlife interface mediated by social and traditional media sources. We take the case study of a reported ‘lioness’ appearing in the outskirts of Berlin as a risk to human and domestic animal life, sparking media frenzies.

Methods. The subjects’ reactions to and perceptions of risk can be analysed through a mixed-methods (quantitative and qualitative) approach to information obtained via the respective media channels in covering the phenomenon as a newsworthy event of  this research identifies three distinct peaks in public interest and response.

Results. Following a Foucauldian tradition of problematisation, and a scholarship of critical media studies, we demonstrate that the ordering of animals in relation to society allows for a normalisation of certain threats from      human-wildlife conflict while placing others in a state of exception which needs immediate action. We do not take the social conditions of predator-prey relations as a given, but seek to ‘de-normalise’ them and question the level of risk constructed, which plays out across public and media spheres and may carry over into human-wildlife conflicts. Our case study shows how social media posts can lead to the emergence of a perceived risk to society, which is reacted to dramatically, and whose emergency situation becomes a newsworthy event that confirms and seems to justify the level of security measures taken. The engagement of citizens online and with the emergency response teams can be viewed as overreacting to the situations based on having a real sense of danger of a ‘lioness’ penetrating their interactions with larger wildlife.

Conclusions: That is, until it is determined that no immediate risk exists, and the actions taken are critiqued as a hysterical misinformed approach of ‘city dwelling’ officials lacking knowledge of wildlife in one’s region. We then speculate about what ethical and political repercussions this may create for multispecies co-existence with predators and pests in Germany.
Attitude of young women aged 18-30 to menstrual tracking apps
Authors: Kuźma Dominika , Papierkowska Roksana
Published: November 2023

Aim. The aim of this article is to explore the attitudes of young women towards menstrual cycle tracking applications.

Methods. The study involved 85 women aged 18 to 30 years to investigate their experiences and opinions regarding the use of menstrual tracking apps. In this work, the method of diagnostic survey was used.

Results and conclusion. The vast majority of respondents use apps to track their menstrual cycle. The most frequently mentioned applications are: Flo and Clue. Respondents who do not use these applications cite as the main reason that they did not know about the existence of such applications or do not like the format. The study shows that most respondents learn about these types of applications from the Internet. The vast majority of surveyed women report that the application correctly monitors the menstrual cycle and use it mainly for this purpose.

Cognitive value. The cognitive value of this article is that women aged 18-30 often use menstrual cycle tracking apps and find them useful but also most of the respondents confirm the credibility of the application in monitoring the menstrual cycle.
Dyscyplina sprawowania liturgii z 1962 roku według motu proprio „Traditionis custodes” papieża Franciszka oraz „Responsa ad dubia” Kongregacji Kultu Bożego i Dyscypliny Sakramentów (cz. 1)
Authors: Pietras Dawid
Published: November 2023

Decyzją papieża Franciszka dokonano zmian w dyscyplinie celebracji liturgii według ksiąg z 1962 roku zwanej dotąd nadzwyczajną formą rytu rzymskiego. Dokonało się to poprzez ustawodawcze normy papieskiego motu proprio Traditionis custodes z 16 lipca 2021 roku – dekretu generalnego biskupa rzymskiego jako najwyższego ustawodawcy. Papieska ustawa została autentycznie zinterpretowana poprzez Responsa ad dubia Kongregacji Kultu Bożego i Dyscypliny Sakramentów z 4 grudnia 2021 roku. Celem wydanych dokumentów, co dookreślił papież Franciszek, było ujednolicenie liturgii w Kościele łacińskim oraz ułatwienie procesu umacniania jedności eklezjalnej.

Published: November 2023

Стаття присвячена дослідженню теоретичних аспектів конкурентоспроможності національних
брендів індустрії гостинності. Проаналізовано роботи вітчизняних та закордонних вчених, які працюють в даній сфері, виявлено основні відмінності в напрямах дослідження. Погоджено власне бачення визначення терміну «національний бренд» як сукупність відмінних та унікальних елементів або характеристик, які уніфікують сприйняття країни в міжнародній економічній системі та вирізняють її з-поміж інших країн. Виявлено, що головними особливостями брендингу в Україні є: легкість створення та просування нових продуктів споживачами та низька впізнаваність існуючих брендів; складність формування у покупців певної лояльності до продукту; значна кількість контрафактної продукції та шахрайства; зростаюча недовіра до реклами; використання в рекламних кампаніях національної символіки, менталітету та звичаїв; значна кількість світових брендів. Визначено найдорожчі бренди ресторанної галузі у 2023 році якими є: Starbucks, Texas Roadhouse, Jollibee та Greggs. Систематизовано та узагальнено основні проблеми української галузі гостинності, названо шляхи їх рішення. Показано, що одним із потужних шляхів позиціонування виступають національні свята видів страв.
Exploring Local Labor Markets and Knowledge Spillover from a Spatial Perspective
Authors:   Ural Federal University, Ekaterinburg, Russia, Wijayanti Febry ,   Universitas Negeri Malang, Malang, Indonesia
Published: November 2023

Relevance. Cities serve as vital hubs for socioeconomic activities, fostering convergence in local labor markets characterized by high productivity, premium wages, and knowledge spillover. Jakarta Metropolitan, as Indonesia's economic center, embodies these advantages, prompting the need for a spatial investigation of their regional association. Research Objective. This study examines the unique attributes of the labor market in the Jakarta Metropolitan Area. The analysis encompasses anomalies such as the impact of premium wages on local labor productivity and the influence of education levels, as a proxy for knowledge spillover, on urban labor productivity. Data and Methods. Utilizing microdata from Sakernas and macrodata from BPS for 2017-2019, this study offers a comprehensive analysis of the Jakarta Metropolitan Area. By synthesizing cross-level data, the intricate interplay between productivity, wages, and area size becomes evident, particularly the tendency for skilled individuals to gravitate toward larger urban centers. Employing spatial regression, the analysis takes into account local characteristics in regions. Results. Density and education have a positive correlation, while the number of holders of bachelor's degrees has a surprisingly negative impact on productivity. Notably, higher aggregate education levels enhance regional productivity throughout the Jakarta Metropolitan Area, except for highly educated individuals. The level of education influences the minimum wage in a region, driven by spatial disparities in the educational infrastructure and quality. The number of educated people also influences wages in and across regions, prompting migration to regions with higher salaries. Conclusions. By integrating microdata and macrodata and employing spatial regression techniques, this study shows the connection between education, productivity, and regional dynamics, particularly in the Jakarta Metropolitan Area. These findings challenge the assumption that possessing a high level of education guarantees higher productivity and remuneration, demonstrating the need for education reforms that align with labor market demands and bolster the economy.
