Steering a Restrictive Course: Rebooting China’s Charity Law
Authors: Sidel Mark
Published: December 2024

When it comes to regulating nonprofits and civil society, China is steering a careful and conservative course in the Xi Jinping era, with a laser-like focus on control over civil society. This policy is illustrated clearly in the long-awaited 2023 amendments to the main law that governs the Chinese nonprofit sector, the Charity Law originally enacted in 2016. This article analyzes the key amendments to the Charity Law in 2023, with a focus on implications for charity regulation and management in China.
Photon balance in the fiber laser model
Authors: Barmenkov Yuri , Minguela-Gallardo Josué A. , Muniz-Cánovas Pablo , Aboites Vicente
Published: December 2024

In this article, we present the results of the numerical study related to the balance of photons in a fiber laser simulated by the traveling wave model (TWM). This study is essential since the balance of photons is closely related to the fundamental physical law of conservation of energy. For generality, we consider that active ions of the gain fiber present excited state absorption at both the laser and pump wavelengths and the fiber background loss. We compare the results of simulation based on the TWM, in which the radial distributions of the populations of the energy levels of the active ions are accounted for, with those obtained when these distributions are omitted. We show that, in the first case, the balance of photons is wholly preserved, while in the second case, the balance of photons is disturbed by tens of percent. The physics behind this result is discussed.
The effect of social exclusion on pain perception and heart rate variability in healthy controls and somatoform pain patients
Authors: Kleber Fabrice , Reif Andreas , de Greck Moritz
Published: December 2024

Objectives

The overlapping neural networks of social and physical pain have been investigated intensively in recent years. It was postulated that triggering social pain might result in greater physical pain. Nonetheless, how this affects somatoform pain disorder has not yet been considered. Since an increased pain processing activity is reported in these patients, the investigation of social exclusion and its effect on this group seems interesting. Hence, the aim of this study was to compare the influence of social exclusion on healthy controls and patients with somatoform pain disorder.

Methods

Nineteen patients with somatoform pain disorder and 19 healthy controls were examined. Cyberball, a virtual ball-tossing paradigm, was used to experimentally induce social exclusion and inclusion. To measure effects on pain perception, pressure pain thresholds and heart rate variability (HRV) were recorded after each round of cyberball. Demographic data, pain medication, and potential psychosocial moderators were collected by questionnaires.

Results

After social exclusion, pressure pain thresholds were significantly reduced in healthy controls (p < 0.01) as well as somatoform pain patients (p < 0.05), while HRV increased only in patients with somatoform pain disorder (p < 0.05) indicating increased parasympathetic activity.

Conclusion

This study is the first to analyse the effects of social exclusion on pain perception in somatoform pain disorder. While the reduction in pressure pain thresholds is in line with the social pain literature, the effects on HRV could be interpreted as a form of pain regulation mechanism. However, further research is needed to investigate the role of parasympathetic activity in socially excluded somatoform pain patients.

Authors: Roblero Mazariegos Gudiel , Pérez Moreno Isaac
Published: December 2024

Las clases de estadística aportan al desarrollo de competencias del universitario, mientras que la percepción de éstos sobre la enseñanza puede incidir tanto en su aprendizaje como en decisiones institucionales. Por ello, el objetivo es analizar la actitud estudiantil hacia la estadística en una universidad privada del sureste de México. El estudio fue descriptivo transversal, donde se consideró una muestra de 111 estudiantes; la recolección de datos se hizo mediante la Escala de Actitud hacia la Estadística (EAE), con respuestas Likert. El instrumento fue aplicado de manera electrónica, y los datos se analizaron con Jamovi. Los hallazgos revelaron un nivel medio (M = 3.21) de actitud hacia la estadística y diferencias significativas acerca del temor hacia ésta, según el área de conocimientos, así como la percepción de necesidad en la profesión y predisposición positiva y activa por género. La literatura muestra distintos escenarios de actitud hacia la estadística, y algunos de ellos coinciden con los hallazgos del presente estudio.

Authors: Hardtke Corpes Andreina
Published: December 2024

O Frigorífico Anglo de Pelotas, normalmente visto como um ambiente de trabalho masculino, abrigou centenas de trabalhadoras, que circulavam diariamente por aquele espaço, exercendo os mais diversos ofícios, ao mesmo tempo em que tinham de lutar para ter os seus direitos básicos respeitados. E, mesmo após passarem a ser amparadas pela Consolidação das Leis do Trabalho (CLT), a partir de 1943, essas mulheres continuaram sendo demitidas, principalmente quando ficavam grávidas. Dessa forma, o seguinte trabalho buscou, através da análise documental de três processos do acervo da Justiça do Trabalho, salvaguardados no Núcleo de Documentação Histórica da UFPel (NDH-UFPEL), contar parte da luta dessas mulheres, especialmente daquelas que tiveram que acessar a Justiça após serem demitidas por estarem grávidas e por terem o auxílio maternidade rejeitado pela empresa.

Impulse response of auction price by practicing auction scheme for solar PV generation to generation quantity, investment and Brent crude oil price
Authors: Shahi Md. Tanvir Alam , Somosi Sarolta
Published: December 2024

Energy is crucial for economic progress worldwide, regardless of a country’s development status. However, the negative impacts of traditional energy sources have prompted global policymakers to reconsider fossil fuel consumption patterns. In addition to these harmful effects, regional conflicts such as the Russia-Ukraine war and tensions involving Israel, Palestine, and Iran are contributing to instability in the global energy market, which in turn affects general market stability. Consequently, global leaders are focusing on country-specific energy policies that prioritize the transition to renewable energy sources in future energy strategies. To ensure the widespread and cost-effective use of solar photovoltaic energy, many countries, including those in the European Union and beyond, are increasingly utilizing renewable energy auction techniques. Thus, the primary focus of this study is to evaluate the impact of a competitive auction technique on the expansion of solar PV generation and the potential reduction (or stabilization) of Brent crude oil prices (i.e., West Texas intermediate oil price). This is particularly relevant given the shifting investment trends in the renewable energy sector, with a specific emphasis on seven open and dynamic economies within the EU. To conduct this analysis, the authors employed a panel vector autoregression (VAR) model, utilizing annual data spanning from 2000 to 2021. The result indicates that the competitive auction value for solar PV accelerates the generation of solar PV in the selected EU countries and the countries are likely to decrease their reliance on fossil fuel-based sources for electricity generation. Because, the auction price is becoming competitive to the Brent crude oil price. Further, the investment in the solar PV sector is not sufficient yet.
The role of workplace spirituality and spiritual leadership in promoting ethical behaviour in the South African small business environment
Authors: Hlatywyao Mangaleni , Van der Walt Freda
Published: December 2024

The rise of unethical leadership practices suggests a need to emphasise value-based workplaces and leadership, encompassing workplace spirituality and spiritual leadership. Most previous research focusing on ethical behaviour in the work context has been conducted with larger organisations. This study examines the influence of workplace spirituality and spiritual leadership on ethical behaviour within the small business context. A quantitative survey research design was employed. The final sample consisted of 385 employees of small, medium, and micro enterprises (SMMEs) in various industries in a central district of South Africa. Structural equation modelling was utilised during the data analysis process. The study revealed that workplace spirituality and spiritual leadership had a positive and statistically significant influence on ethical behaviour in SMMEs, and workplace spirituality mediates the relationship between spiritual leadership and ethical behaviour. The study extends on existing literature as this relationship has previously not been investigated in the African small business context. Also, the findings hold practical significance for small businesses struggling with unethical behaviours and leadership. The findings of the study imply that a culture of spirituality in the workplace enhances the impact of spiritual leadership in promoting ethical behaviour in the small business environment.
Pursuing a communitarian ethic for corporate governance to strengthen health promotion: A scoping review
Authors: King Judith , Gaede Bernhard , Ndlovu Noluthando
Published: December 2024

The magnitude of South Africa’s diet-related non-communicable disease burden calls for scrutiny of sugar-sweetened beverage manufacturers’ business ethics in terms of the commercial determinants of health. We gathered and analysed relevant literature from five electronic databases to determine whether a communitarian ethic can strengthen corporate governance in support of public health. Twenty-nine of 648 results were selected for data extraction and analysis. Six thematic categories were identified: the reciprocal nature of the corporation in society; perspectives on ‘corporate citizenship’; integrative approaches to corporate sustainability; critiques of Corporate Social Responsibility; legal regulation to engender communitarian consciousness; and the social contract perspective. We found that in tackling the human and economic toll of South Africa’s obesogenic environment, a diverse range of theoretical and practical perspectives supports the concept that a communitarian ethic for corporate governance can normalise accountability for population health as a human right.

Authors: Martínez Pérez Sandra
Published: December 2024

The Practicum of the Degree of Pedagogy of the University of Barcelona is composed of three essential subjects: Professionalization and Work Exits, Practices of Professional Initiation and External Practices. Through the research project The employability of the pedagogue: a necessary synergy between the organizations of practices and the University (REDICE 14- 1126), whose main purpose is to build a knowledge transfer community incorporating the participation of the tutors of the institutions’ practices, as key elements in the process of professional development of the professionals of the Pedagogy, it is tried to rethink the relations of knowledge transfer between the university and the organizations of practices. For this purpose, discussion groups, interviews and a questionnaire have been designed in order to collect the experiences and perceptions of the tutors. The results obtained from the analysis of the techniques and instruments used indicate 6 basic axes: 1) the importance of coordination, exchange and dialogue between all parties, which consists of sharing teaching plans, studies and know the needs of organizations; (2) the creation of a community of practice in which organizations have a relevant role; 3) the need for a mutual commitment: social responsibility, which takes into account labor competencies, market demands and career opportunities; 4) concern for the students, as the protagonist of their own process; 5) the availability of being a nearby university, which is open to society and; 6) training and counseling as mutual enrichment. All this will lead to the creation of a community manager in a virtual platform, offering a horizontal communication space and an agile, functional and open organizational structure.
Actitud hacia la Homosexualidad (EAH-10) en el Alumnado Universitario
Authors: Conde-Vélez Sara , Sala Millán Francisco , Delgado-García Manuel , Márquez Díaz José Ramón
Published: December 2024

Este trabajo profundiza en el análisis de las actitudes del alumnado universitario hacia el colectivo homosexual. Se ha utilizado la Escala de Actitud hacia la Homosexualidad (EAH-10) con el objetivo de estudiar la relación entre dicha actitud con algunas variables sociodemográficas; también se han analizado algunas de sus propiedades psicométricas. Se expone una investigación de tipo encuesta en la que han participado 693 estudiantes de la Universidad de Huelva (España). Los resultados demuestran que las actitudes en las que se intuye un mayor rechazo hacia la homosexualidad son las que se corresponden con el género masculino, con aquel alumnado que se considera creyente, quienes se definen como heterosexuales y quienes estudian en titulaciones técnicas. También se ha podido comprobar que la escala mejora considerablemente al suprimir varios ítems (aunque se ratifica la estructura original de dos factores: aceptación y rechazo) obteniendo un Alfa de Cronbach de 0,83. Como conclusión, se advierte necesario plantear acciones educativas más inclusivas para integrar en los planes de estudios universitarios una formación en igualdad y diversidad sexual.

This study assessed the feasibility of using major agricultural residues specifically bagasse, rice straw, wheat straw, and coir fiber to produce single-layer particle boards. These boards of densities 300, 400, and 500 kg/m³ were developed using melamine urea formaldehyde resin. Comprehensive evaluation of the boards included determination of their sound absorption coefficient (SAC), thermal conductivity, and noise reduction coefficient (NRC), as well as various physical properties and modulus of rupture. Additionally, the impact of board density on the SAC across a frequency range of 50 to 5000 Hz was examined. The coir boards displayed superior SAC, particularly at 3000 Hz. Rice straw boards at a density of 300 kg/m³ exhibited the lowest thermal conductivity (0.098 W/m-K). Density of 300 kg/m³ was optimal for achieving the highest SAC and lowest thermal conductivity in agro residue particle boards. As the density of the boards increased, SAC decreased, whereas thermal conductivity (K) increased, indicating that lower-density boards are more effective as sound and thermal insulators. Furthermore, all particle boards demonstrated promising sound absorption capabilities, achieving classifications of D and E under ISO 11654:1997, making them viable for interior applications in the building industry.
Dimensional analysis of absorbency in paper towels: A study of three- and two-dimensional mechanisms
Authors: Kweon Soon Wan , Kang Na Young , Kim Hyoung Jin
Published: December 2024

The dimensional absorbency properties of paper towels were studied, focusing on three- and two-dimensional absorption mechanisms. Key factors affecting these absorption mechanisms were identified through a series of experiments and principal component analysis (PCA). The results showed that the water absorption capacity, driven by capillary action (porosity), exhibited differences between two-dimensional surface absorption (in the X and Y directions) and three-dimensional bulk absorption (including the Z direction, or thickness). Porosity analysis revealed that three-dimensional absorbency is highly correlated with porosity, whereas two-dimensional absorbency has a relatively low correlation and is influenced by fiber properties such as length and width, as well as mass-related characteristics including fines content and freeness. The findings highlight the need to balance these dimensional properties to achieve optimal absorbency in paper towel products. Additionally, this study provides a foundation for developing more efficient paper towels and offers valuable insights into the complex mechanisms of paper towel absorbency, which will aid in the development of improved hygiene paper products.

This study analyses the volumes of plastic, polyethylene, and waste tires generated in Ukraine and assesses the potential for obtaining alternative fuels from these wastes. This waste is accumulating rapidly around the world, and Ukraine is no exception. Therefore, the purpose of this study is to determine the potential for obtaining domestic alternative fuels from waste plastic, polyethylene, and waste tires. The subject of study is the encompasses waste plastic, polyethylene, and waste tires. The subject of the study is waste plastic, polyethylene, and worn-out tires, and their energy potential for alternative fuel production. The working hypothesis of the study is that the establishment of an environmentally friendly collection and processing of these wastes can partially resolve the energy situation in the country. A systematic review of existing studies was chosen as the research method, as official data from the State Statistics Service of Ukraine does not fully reflect the current state of waste generation. The study revealed the following. The volume of plastic waste generated in Ukraine annually ranges from 990 thousand tonnes/year to 1820 thousand tonnes/year, with an average of 1405 thousand tonnes/year. Accordingly, the amount of fuel that can be obtained from plastic waste ranges from 297 thousand tonnes/year to 1729 thousand tonnes/year. Every year, 3–4.1 million tonnes of polyethylene waste remains unrecycled. The potential for producing fuel from polyethylene waste ranges from 1500 thousand tonnes per year to 3700 thousand tonnes per year. Ukraine generates 225–360 thousand tonnes of unused worn-out tires annually. The potential for obtaining fuel from waste tires ranges from 67.5 thousand tonnes per year to 180 thousand tonnes per year. Thus, the total potential for obtaining motor fuel from waste plastic, polyethylene, and waste tires ranges from 1864.5 thousand tonnes/year to 5609 thousand tonnes/year and indicates the need to establish environmental management of these wastes in Ukraine. The proposed hypothesis has been substantiated by the results of these studies.

Additive manufacturing significantly impacts the energy sector through its ability to form complex geometries and optimize designs, enhancing the performance and reliability of energy systems and complexes. This type of manufacturing allows the creation of optimized parts considering energy efficiency and durability requirements, for example, heat exchangers can be designed and manufactured with a unique structure to improve their efficiency, and new energy devices and systems can be quickly prototyped for testing and optimization before mass production. The use of additive manufacturing can make parts production for energy complexes more localized and flexible, which is particularly beneficial when creating small and medium-sized energy systems. The paper discusses technologies for quality control of additive manufacturing products in the process of printing elements of energy complexes. Describes the state-of-the-art methods and controls used to ensure the high quality of 3D printed parts required for efficient operation of energy systems. Various aspects of inspection are covered, including printing process monitoring, flaw detection, material structure analysis, and geometric inspection. Examples are given of the use of various quality control methods in the context of the production of elements for energy complexes, making the article relevant for specialists in the field of additive manufacturing and energy. An analysis of existing printing technologies was carried out, and the advantages and disadvantages of each technology that is used in the process of serial production of additive manufacturing products for elements of power plants and complexes were highlighted.
Keywords: technologies ofadditive manufacturing, additive manufacturing quality control software,artificial intelligence, energy complexes.
La recepción del bombardeo de Guernica en la prensa francesa
Authors: Bessac-Vaure Stève
Published: December 2024

El bombardeo de Guernica, el 26 de abril de 1937, rápidamente encontró un eco internacional. De inmediato surgió la cuestión de la responsabilidad de este acto de guerra contra una población civil, desarmada e inocente. La prensa francesa participó en este debate. Sin embargo, en lugar de llevar a cabo una investigación seria, los periódicos (el diario comunista L’Humanité pero también el periódico conservador Le Figaro) analizaron el acontecimiento según sus propias ideas políticas. Por su parte, las publicaciones católicas fueron sacudidas en sus convicciones éticas: La Croix, una publicación de derecha, vaciló en reconocer la responsabilidad del bando franquista y de sus aliados, mientras que la revista Esprit denunció el mito de la Cruzada. El bombardeo de Guernica constituyó así una crisis en el catolicismo francés.
Wissenschaftliche „jam session“ oder „Dubrovnik-Disco Libertas“
Authors: Schmuck Lydia
Published: December 2024

Die von Hans Ulrich Gumbrecht von 1981 bis 1989 veranstaltete Kolloquiumsreihe in Dubrovnik machte bereits vor der Wende Theoriediskussionen zwischen Wissenschaftler*innen aus Ost und West möglich. Die Kolloquien waren durch Interdisziplinarität und Internationalität gekennzeichnet, aber auch durch die hohe Beteiligung von Frauen und Nachwuchswissenschaftler*innen. Neben neuen Inhalten stehen die Kolloquien auch für eine neue Form: Statt einzelner Vorträge standen gemeinsame Debatten im Mittelpunkt. Daher wurde die Kolloquiumsreihe auch als „wissenschaftliche ,jam session‘“ oder „Dubrovnik-Disco Libertas“ bezeichnet. Wegen der schwierigen Materiallage, die auch mit der Mündlichkeit der Debatten begründet ist, sind die Kolloquien bisher kaum erforscht. Auf Basis verschiedener, teils noch nicht öffentlich zugänglicher Materialien, wird mit dem Artikel eine erste Charakterisierung und Einordnung vorgenommen.
The use of transitive Montgomery indicators for scanner data analysis
Authors: Białek Jacek , Pawelec Natalia
Published: December 2024

Although the modern price index theory is based on an analysis of ratios of prices
and quantities, one may be often more interested in working with differences in these
values in many economic areas, e.g.: revenue change decompositions, profit and cost
change decompositions, or an analysis of changes in consumer surplus. The benefit of
using these differences is that there is no problem associated with the occurrence of
zero prices and quantities, a problem that arises when working with ratios. In practice,
one mostly cares about decomposing the value difference into indicators of contributions
from price and quantity differences. The well-known price and quantity indicators are
the Bennet and the Montgomery indicators, which are not transitive. This paper revises
the price and quantity Montgomery indicators and their multilateral versions for the
analysis of scanner data. Specifically, instead of considering ‘classical’ comparisons
across firms, countries or regions, the transitive versions of the Montgomery indicators
were adapted to work on scanner data sets observed over a fixed time window. One of the
objectives of the study was to compare bilateral and multilateral Montgomery indicator
values for different data aggregation levels and three main types of data filters. To
the best of the authors’ knowledge, this study is pioneering on the grounds of
implementing the multilateral Montgomery indicators in scanner data analysis.
Was tax optimisation used in ancient Japan?
Authors: Jerzemowska Magdalena Katarzyna
Published: December 2024

The aim of this paper was to investigate whether tax optimisation was used in
ancient Japan. The period under consideration covered the Yamato (250-710), Nara
(710-794), and Heian (794-1185) epochs, i.e. the ten-century period including the
building of the centralised state, the establishment of the Ritsuryō state, and its
disintegration. The analysis of these three stages was made in terms of the use of tax
optimisation. The most important taxes, principles of their measurement, collection and
effectiveness were discussed, distinguishing three levels of tax optimisation – state,
local and basic. The study aimed to verify the thesis that tax optimisation was used in
ancient Japan. The method of research was the analysis of relevant literature. This
analysis is one of the first attempts in Polish literature to outline the system of
taxes and its evolution in ancient Japan. Another novelty is the indication of the
possibilities of tax optimisation on three levels – setting tax policy (the state),
assessing, and collecting taxes (local), and basic – generating tax revenues (farmers
and artisans). This research showed that tax optimisation has been practised in Japan
since the establishment of the Ritsuryō state, and also revealed that some of the old
tax principles and practices are still applied in the modern Japanese economy. This
study contributes to narrowing the research gap in Polish economic literature on
taxation in ancient Japan and points to the need for further exploration of this
interesting and still relevant research area.
Nonpayers also matter. On Lintner’s dividend partial adjustment model estimation
Authors: Kowerski Mieczysław
Published: December 2024

The dividend partial adjustment model proposed by J. Lintner (1956) is still one
of the most widely used tools for analysing the dividend policy of companies. This model
should be estimated only on the basis of observations in which dividend payments were
recorded. This causes the sample selection to be not random and so the parameters
estimator of the Lintner’s model to be inconsistent. However, the level of the payouts
of the companies selected for the Lintner’s model may be affected by the decisions of
dividend nonpayers not selected for this model. Some authors noted this contradiction,
but there are no effective methods to solve it. In the article, to solve this problem,
the Heckman (1976) sample self-selection model was proposed, which consists of two
equations: the participation equation, which is a probit model of the propensity to pay
dividends, and the outcome equation, which is Lintner’s partial adjustment model. This
was examined using an unbalanced panel of 112 companies listed on the Warsaw Stock
Exchange. The results of the estimation of the Heckman model confirm that the inclusion
of information about companies not paying dividends in the Lintner’s model results in a
significant reduction of the dividend target payout ratio and speed of adjustment.
Estimated target dividend payout ratio and the speed adjustment for the entire market
may be important information for companies’ management when developing their own
dividend policies.
Causal linkages between stock, crude oil and gold returns in Central Europe
Authors: Mamcarz Katarzyna
Published: December 2024

The aim of this paper was to evaluate the relationship between the stocks, crude
oil and gold markets of Central Europe in the short and long-term by applying a vector
error correction model (VECM), and the Granger-causality analysis followed by a forecast
error variance decomposition (FEVD) and impulse response function (IRF) analysis. Since
gold seems to demonstrate a low or negative correlation with stocks, while the
correlation between crude oil and gold is positive, it is important to investigate the
interrelations in the markets in question to understand the nature of the linkages
between them and their implications. It is assumed that there exists a long-term
equilibrium between the analysed assets and that the changes in the prices in the gold
and crude oil markets impact the stock market. The research findings confirm a long-term
relationship between the markets as the prices of the analysed assets are cointegrated.
In the long-term, the increase in the crude oil price (Brent) caused a raise in the gold
price, whereas the impact of the stock price (Central European Blue Chip Index CETOP)
was opposite. The author indicated two cases of unidirectional causality, hence the gold
returns Granger-cause the stock returns, as expected. However, the latter determined the
crude oil returns, which contradicts the research hypothesis. One can observe the
negative impact of gold returns on the stock returns, whilst the stock returns have a
positive impact on the crude oil returns. To the best of the author’s knowledge, no
similar research with the use of VECM was devoted to the interrelations between the
stock, crude oil and gold markets of Central Europe described in this paper. Most of the
research focused on countries classified as the key producers and consumers of gold.
Analysis of the impact of export specialisation and investment attractiveness on
the processes of innovation diffusion in the processing industry in Poland
Authors: Salamaga Marcin
Published: December 2024

The fundamental ways of building innovativeness of the economy are the creation
and diffusion of innovation, the latter of which is the dispersal of new technological,
organizational, marketing solutions as well as knowledge among imitator enterprises, and
copycats (the ‘spillover effect’). Important determinants of innovation diffusion
include the inflow of foreign capital (in the form of FDI) and foreign trade. Few
empirical studies exist that attempt to explain the sources of innovation diffusion in
the Polish economy applying quantitative tools used in contemporary statistics and
econometrics. The existing research gap makes it difficult to reliably assess the actual
cause-and-effect relationships between spillover processes and macroeconomic variables.
This article sought to determine the nature and strength of the impact of investment
specialisation (and investment attractiveness) as well as industry export specialisation
on the phenomenon of penetration of innovation in the Polish processing industry. The
occurrence of innovation diffusion and its dynamics were investigated using the logistic
function econometric model. To study the impact of the specialisation, according to FDI
located in Poland, and specialization of export on the process of innovation diffusion,
dynamic models of error correction estimated for selected industrial processing
industries were used. The obtained results allowed to answer the questions: in which
industries has innovation diffusion occurred, in which was it the fastest, and to what
extent was it the effect of investment attractiveness, and to what degree of the export
specialization of the industry?
Determinants and speed of adjustment of financial liquidity: Evidence from Central
and Eastern Europe
Authors: Czerwonka Leszek , Jaworski Jacek
Published: December 2024

The article aims at (i) identifying the financial liquidity determinants at firm,
industry and country level, (ii) examining whether firms follow the target liquidity
level, and (iii) determining the average speed of adjustment to this level. Statistical
analysis was used in an empirical study based on financial data of 13,513 firms
operating in seven countries from Central and Eastern Europe in the research period
2012-2020. The study confirmed company-specific liquidity determinants (company size,
growth, tangibility, leverage and cash flow). The average industry liquidity was found
to be an industry-specific factor (positive relationship). The positive impact of
unemployment and access to credit was detected at country level. The study also showed
that country-specific determinants had twice as broad an influence on liquidity as
industry-specific factors. It also provided evidence that companies tend to achieve the
target liquidity level. The speed of adjustment was 88%.
Novel low-frequency maternal mosaicism mutation of CHRDL1 gene resulted in the X-linked megalocornea in the offspring
Authors: Nguyen Minh Phu , Nguyen Khanh Linh , Nguyen Quang Anh , Nguyen Huu Hong Thu , Nguyen Hai Ha
Published: December 2024

X-linked megalocornea (MGC1) is an inherited disorder resulting from mutations of the CHRDL1 gene. Common symptoms of megalocornea include oversized cornea, deeper fluid-filled space between the cornea and iris, blurred or distorted vision at every distance, leading to mild vision issues. In this report, we present the first cases of megalocornea caused by the maternal low-frequency somatic mosaicism of the novel CHRDL1 mutation. Two Vietnamese siblings, 5 years old (MG001) and 13 years old (MG002) visited the hospital for regular check-ups with manifestations such as myopic, exophthalmia, and enlarged cornea. They were suspected of having inherited megalocornea disorder without glaucoma symptoms. The DNA genome of the proband (MG001) was applied for whole exome sequencing (WES) analysis, and the result revealed a hemizygous pathogenic variant c.943dupA in the CHRDL1 gene, which results in a frameshift mutation (p.Ile315fs) in protein. This mutation was also identified in the proband (MG002) by Sanger sequencing. Notably, the CHRDL1 c.943dupA mutation was recognized at a very low fraction in the maternal DNA after triplicate Sanger sequencing, indicating that the mother has a mosaicism mutation of CHRDL1 c.943dupA. This study reported a rare case of X-linked megalocornea in a family and provides a novel genetic factor relating to an eye disorder in Vietnam.

Pseudomonas aeruginosa (P. aeruginosa) is a common environmental bacterium found in various habitats, including water and soil. Rapid detection of this microorganism is essential for monitoring environmental contamination and assessing its potential impact on ecosystems and public health. This study aimed to develop a high-efficiency loop-mediated isothermal amplification (LAMP) assay targeting a P. aeruginosa-specific gene encoding a hypothetical protein (GenBank ID: 882161). The study involved two main parts: 1) Isolation and identification of P. aeruginosa from environmental samples, and 2) Evaluation of the established LAMP assay on these environmental P. aeruginosa isolates. A total of 52 samples were collected from various geographical regions in Ho Chi Minh City, with 50 samples (96%) containing Pseudomonas species, characterized as rod-shaped, Gram-negative bacteria growing on selective media. Following duplex PCR screening, 14 P. aeruginosa-like environmental strains were isolated, and 5 randomly selected isolates were confirmed as P. aeruginosa through 16S rRNA sequencing. The LAMP assay was optimized at 60°C, 63°C, and 65°C for 30 and 45 minutes, using specific primers, and tested on all five confirmed P. aeruginosa isolates. The results demonstrated that the LAMP assay was highly specific (100%) for detecting environmental P. aeruginosa, with a detection limit of 1 pg/μL. In conclusion, P. aeruginosa is prevalent in the environment, and the developed LAMP assay shows strong potential for identifying environmental P. aeruginosa isolates.

Published: December 2024

Non-governmental entities often facilitate current matchmaking trends, promoting certain ideologies that may contradict the Islamic family law model introduced by the state. In response, Surakarta’s Ministry of Religious Affairs launched the "Samawa Program: Make Me Your Partner" to support matchmaking, especially amid limited mobility during the COVID-19 pandemic. This article uses a philosophical approach to examine this program’s goals, rules, and strategies and how it aligns with Jeremy Bentham’s legal utilitarianism theory. The article finds that this free of charge program provides marriage guidance practices distinct from regular marriage counseling practices at the Office of Religious Affairs. The program’s objective is for individuals to get marriage guidance as a foundation for building a family and to find a partner who meets their criteria. Considering Bentham’s seven indicators of happiness and pain levels, the program fully satisfies the intensity, duration, proximity, and fecundity benefit aspects. However, it can potentially generate harm regarding the other three elements: certainty, purity, and extent. At this stage, the program is considered highly beneficial, serving as an effective facilitation tool for individuals seeking compatible partners. It not only ensures a satisfying matchmaking experience but also provides quick, credible access to essential marital knowledge.
Muslim Families' Resilience Post-Eruption Mount Semeru: The Quest of Women’s Roles in Family
Authors: Shofi Muhammad Aminuddin , Bin Budin Azmi
Published: December 2024

Women play a crucial role in maintaining family resilience. Their role becomes even more tested in critical situations. This article examines the resilience of Muslim families after the Semeru eruption and highlights the vital role of women in rebuilding family strength in Sumbermujur village, Lumajang, East Java. This article uses a sociological approach, utilizing structural-functional theory. This article reveals that, sequentially, post-relocation, the survivors of the Semeru eruption were impacted economically, psychologically, culturally, and physically. Significantly, they lost assets and faced difficulties finding new jobs, which emerged as the dominant effect. This article shows that women are crucial to building family resilience. From the perspective of structural-functional theory, adaptation is evident in how women must adapt to new physical, psychological, socio-cultural, and economic conditions. This adaptation that aims to achieve family independence and well-being manifests their goals. How women share roles dynamically and flexibly in fulfilling each other's responsibilities reflects integration. The interaction of religious, legal, and social norms that always guide women in performing their roles shows latency. Thus, the role of women in preserving family resilience can be seen as an implementation of their religious responsibilities to achieve a harmonious family in critical situations.

Divorceify is an Artificial Intelligence (AI)-based platform designed to assist in managing divorce processes within a divorce accounting system. However, applying this platform in Indonesia’s legal system may face several challenges. This article examines the extent of Divorceify’s role and influence within the judicial system. It also delves into the challenges and future impacts of using Divorceify in Indonesia’s legal system. Using normative research methods with a conceptual approach, this article asserts that in the context of Indonesian law, the adoption of such technology faces various obstacles, including alignment with local legal frameworks, cultural sensitivities, access and education on technology, and data privacy issues. Indonesia’s legal system can adapt to this innovation in order to improve efficiency and fairness in divorce proceedings, as it is seen as capable of enhancing efficiency, reducing costs, providing fairer outcomes, and alleviating administrative burdens on courts. Additionally, critical obstacles must be addressed to ensure successful integration, especially regarding legal ethics and personal data protection. With the appropriate regulatory, ethical, and technological frameworks, AI-based divorce management tools like Divorceify hold significant potential to improve Indonesia’s judicial system.

Surface bound microgels on the basis of carboxymethylcellulose: preparation via the Ugi reaction and structural investigation using fluorescent and spin labels
Authors: Alqubelat Rita S. , Antonov Denis O. , Mironov Maxim A.
Published: December 2024

A microgel with an average diameter of 368±4 nm was obtained by adding a small amount of polyvinylamine (PVAm) to a 0.3% aqueous solution of carboxymethylcellulose (CMC). The CMC/PVAm microgel particles were deposited on a layer of pure PVAm, which in turn was located on a glass substrate. Four-component Ugi condensation in aqueous solutions at pH 5.0–5.5 was applied to fix the resulted structures. A water-insoluble layer of PVAm gel with CMC/PVAm microgel particles distributed over its surface was obtained. It was shown that at pH 8 the CMC/PVAm gel particles swell, more completely covering the surface of the PVAm gel layer applied to a glass substrate. Fluorescent labels (aminofluorescein moiety) and spin labels (amino-TEMPO moiety) were introduced into the CMC structure in order to monitor this process using fluorescence microscopy and EPR spectroscopy.
A FORÇA DA NÃO-VIOLÊNCIA: CONTRIBUIÇÕES BUTLERIANAS AO CURRÍCULO CULTURAL DA EDUCAÇÃO FÍSICA NO CONTEXTO PANDÊMICO

Published: December 2024

Na sociedade atual globalizada, neoliberal, multicultural e desigual, as tensões políticas, culturais e sociais podem modificar as condutas dos sujeitos e o modo com que passam a olhar a si, aos outros e às coisas do mundo. Por vezes, as práticas de violência são utilizadas como mecanismo de normatização, controle, coerção e condições de morte a certas existências que não compactuam com as normas estabelecidas por grupos que exercem o poder na teia social. A pandemia ampliou o nosso olhar sobre a violência, basta lembrar-se que o retorno ao ensino presencial fez eclodir inúmeros conflitos atrelados à relacionalidade. O presente artigo objetiva pensar a força da não-violência como um princípio ético-político pautado na responsabilidade ética baseada na relacionalidade. No atravessamento dos estudos de Judith Butler em diálogo com o arcabouço teórico do currículo cultural da Educação Física, o artigo fomenta espaços para a criação de possibilidades de uma educação pela forma-de-vida.
