The role of the public policy clause in the Polish legal system on the example of cases concerning the conclusion and dissolution of marriage
Authors: Szczygieł Adrianna
Published: March 2024

The article aims to demonstrate the role of the public policy clause in the Polish legal system in the context of matrimonial relations, with a particular emphasis on the institution of the conclusion and dissolution of marriage. As a part of the discussion, the analysis reconstructs the essence of the public policy clause, while demonstrating the most important principles of family law and conflict-of-law rules concerning matrimonial matters. The author examines the relationship between the public policy clause and family law by emphasising differences in legal systems amongst different nations and specifying the authorised and prohibited implementation of the public policy clause regarding marriage conclusion and dissolution. It is also pointed out that child marriage, polygamy, and divorce through unilateral declaration of will, cannot be reconciled with Polish public order; and attention is drawn to the inadmissibility of establishing restrictions on the freedom to marry on the basis of racial, religious and social criteria. The author’s evaluation utilises case law, academic literature, and opinions from doctrinal representatives on this issue. The conclusion emphasises the significance of the public policy clause in preserving the consistency and uniformity of the Polish legal system as a tool to fight discrimination and gender inequality.
The data subject’s right to access to information under GDPR and the right of the data controller to protect its know-how
Authors: Kuźnicka-Błaszkowsk Dominika
Published: March 2024

The data subject’s right to access information on data processing has a very broad meaning. Considering the latest developments in this field (mainly the CJEU ruling on Austrian posts and EDPB guidelines) one can draw the conclusion that the controller’s right to protect its confidential in-formation is limited and less valuable than the data subject’s rights. However, this may lead to unfair and unequal treatment of companies and data subjects. When looking at this right in a more systematic perspective, it seems that the model of the protection of personal data may go hand in hand with the controllers’ business interests. A different interpretation may lead to the discouragement of entrepreneurs, both EU and foreign, from conducting business in the European Union. This is not conducive to the development of the European market and certainly will not attract foreign capital.

Published: March 2024

Biomass-based aerogels are of interest due to their abundant precursors, ease of functionalization, eco-friendliness, low cost, and effectiveness in dye-contaminated water treatment. Coconut pith (CP) known as a by-product after coconut processing is a sponge-like and lightweight material discarded in large volumes. For the first time, carbon micro-particles resulting from two-step treatment and pyrolysis of CP have been successfully incorporated with chitosan to produce aerogel composites by high-speed homogenization and freeze-drying. After pretreatment, holocellulose content and crystallinity index of the recovered CP pulp are respectively 75.4 and 58.6 % along with a solid recovery rate of 27.5 %. Characteristic properties of the aerogel composites are featured by their density as low as 15.23–28.17 mg/cm3, remarkably high porosity of 98.17–99.05 %, and Young’s modulus of 1.64–12.23 kPa. Synergistic effects of the porous network, electrostatic interactions between both amine groups in chitosan and carbon surface with methyl orange (MO) cause the as-fabricated aerogel composites to achieve an extremely high adsorption capacity of 454.13 mg/g and removal efficiency of 92.32 % at initial MO concentration of 500 mg/L. Therefore, the CP-derived carbon/chitosan aerogel composites synthesized from a feasible procedure exhibit their great potential in enhancing the value of coconut waste and dealing with dye-contaminated water pollution by simple and economical adsorption.

Published: March 2024

Variable-order derivatives are the natural extension of ordinary as well as of fractional-order differentiations and integration, respectively. Numerous suggestions for fractional variable-order operators have been made in the literature over time. Therefore, this is the moment to shine a light on the variable-order fractional calculus, due to the fact that it accurately describes the mathematical underpinnings and emphasizing the modeling utility via using contemporary numerical techniques. This study focuses on investigating a fractional variable-order model of lymphatic filariasis infection using with Atangana–Beleanue–Caputo derivative. Our investigations have led to the development of newly refined results, focusing on both qualitative and numerical aspects of analysis. To achieve our research objectives, we employ the fixed point theorems of Banach and Krasnoselskii. These theorems serve as powerful tools, allowing us to establish results regarding the existence of solutions to the model. Additionally, for precise numerical simulations, we employ the fractional Euler’s method, a sophisticated computational technique that allows us to effectively simulate and interpret the results both numerically and graphically. These graphs illustrate distinct variable-orders, providing a comprehensive understanding of the model’s behavior under different conditions. Here, it should be kept in mind that we have select various continuous functions for variable to present our graphical illustration.

Published: March 2024

The condition of intolerance to uncertainty in individuals arises when there is a possibility of a bad situation or having a risky future. Therefore, many individuals try to reduce these adverse effects that may occur in the future by believing in superstitions. This research will reveal whether there is a superstitious belief in intolerance in uncertain conditions. Data will be analyzed using Pearson Product Moment involving 395 subjects selected through quota sampling. The results showed that there was a relationship between superstitious beliefs and intolerance of uncertainty with a correlation strength of 0.423. This means that when an individual is in an uncertain situation, it can trigger the presence of intolerance of uncertainty. On the other hand, the presence of superstitious belief is believed to have existed in the individual and tends to be used as a protector in making decisions.

Authors: Perdana Muhamad Putra , Abidin Zaenal
Published: March 2024

Purpose: The study aims is to examine the determinants that impact the level of public interest in utilizing mobile health (m-health) applications in Semarang City, Indonesia. Our specific objective is to identify the critical factors that facilitate or impede the public's adoption of these applications.Methods: This study objective was pursued using a comprehensive approach. A study model was developed utilizing the Unified Theory of Acceptance and Use of Technology (UTAUT) as its foundation. This model encompasses essential variables including performance expectancy, effort expectancy, social influence, facilitating conditions, price value, and perceived trust. The process of data collecting was carried out by means of a survey that was disseminated across widely used social media channels. The study was conducted using a sample size of 257 participants who are residents of Semarang City. The data that was collected underwent a thorough analysis utilizing the Partial Least Squares - Structural Equation Model (PLS-SEM) approach.Results: The research conducted in our study resulted in several significant findings. The study revealed that several factors, namely performance expectancy, social influence, price value, and perceived trust, had a notable and beneficial impact on users' inclination towards using m-health applications. On the other hand, the variables of effort expectancy and facilitating conditions did not exhibit a statistically significant influence on the level of public interest in these applications. Furthermore, a substantial correlation was found between the behavioral intention and the actual usage behavior of inhabitants of Semarang City in their adoption of m-health applications.Novelty: The research presented in this study is distinguished by its comprehensive analysis of the various factors that impact the adoption of mobile health (m-health) applications in Semarang City. Through the incorporation and expansion of variables such as price value and perceived trust, our study provides a comprehensive and nuanced comprehension of this particular occurrence by adapting and extending the UTAUT model.

A Comparative Study of Random Forest and Double Random Forest Models from View Points of Their Interpretability
Authors: Khairunnisa Adlina , Notodiputro Khairil Anwar , Sartono Bagus
Published: March 2024

Purpose: This study aims to compare the performance of ensemble trees such as Random Forest (RF) and Double Random Forest (DRF) from view points of interpretability of the models. Both models have strong predictive performance but the inner working of the models is not human understandable. Model interpretability is required to explain the relationship between the predictors and the response. We apply association rules to simplify the essence of the models.Methods: This study compares interpretability of RF and DRF using association rules. Each decision tree formed from each model is converted into if-then rules by following the path from root node to leaf nodes. The data was selected in such a way that they were underfit data. This is due to the fact that DRF has been shown by other researchers to overcome the underfitting problem faced by RF. A Simulation study has been conducted to evaluate the extracted rules from RF and DRF. The rules extracted from both models are compared in terms of model interpretability based on support and confidence values. Association rules may also be applied to identify the characteristics of poor people who are working in Yogyakarta.Result: The simulation results revealed that the interpretability of DRF outperformed RF especially in the case of modelling underfit data.  On the other hand, using empirical data we have been able to characterize the profile of poor people who are working in Yogyakarta based on the most frequent rules.Novelty: Research on interpretable DRF is still rare, especially the interpretation model using association rules. Previous studies focused only on interpreting the random forest model using association rules. In this study, the rules extracted from the random forest and double random forest models are compared based on the quality of the rules extracted.

Published: March 2024

Purpose: As the complexity and diversity of cyberattacks continue to grow, traditional security measures fall short in effectively countering these threats within web-based environments. Therefore, there is an urgent need to develop and implement innovative, advanced techniques tailored specifically to detect and address these evolving security risks within web applications.Methods: This research focuses on analyzing attack detection in log access servers using machine learning classification with two primary approaches: expert labeling integration and best model selection. Expert labeling determines whether log entries are safe or indicate an attack.Result: Validation in labeling was applied using different datasets to minimize errors and increase confidence in the resulting dataset. Experimental results show that the Decision Tree and Random Forest models have nearly identical accuracy rates, around 89.3%-89.4%, while the ANN model has an accuracy of 81%.Novelty: This study proposes a fusion of expert knowledge in labeling log entries with a rigorous process of selecting the best classification model. This integration has not been extensively explored in previous research, offering a novel approach to enhancing attack detection within web applications. The research contribution lies in the integration of expert security assessment and the selection of the best model for detecting attacks on server access logs, along with validating labels using various datasets from different log devices to enhance confidence in the analysis results.

Authors: Alnasrallah Noor , Aljenaee Khaled , AlMurshed Maryam , Hajji Sulaiman
Published: March 2024

Gonadotroph adenomas are the most common type of nonfunctional pituitary adenomas. However, functioning gonadotroph adenomas causing clinical manifestations are rare. We present the case of a 42-year-old man with an incidental finding of a pituitary gland mass. A pituitary MRI revealed a 3 cm macroadenoma, and laboratory investigations revealed elevated follicle-stimulating hormone (FSH) and total testosterone levels. A diagnosis of functioning FSH-secreting pituitary adenoma was considered, with possible concomitant luteinizing hormone secretion, given the elevated testosterone, prompting further evaluation. Testicular ultrasound showed bilaterally enlarged testicles, and visual field testing revealed a monocular superior temporal defect. Transsphenoidal resection of pituitary adenoma was the treatment of choice. Histopathology assessment confirmed the diagnosis of gonadotroph-secreting adenoma, with positive staining for FSH. Within the 12-week postoperative period, FSH and testosterone levels normalized, and the patient experienced significant improvement in vision, along with the resolution of macroorchidism. While functional gonadotroph adenomas are rare, patients can present with a wide range of symptoms that are often unnoticeable due to their slow development. Careful evaluation can help guide multidisciplinary management to achieve full remission.

Learning points

Endocrine evaluation is indicated in all cases of pituitary incidentalomas to determine functional status.

Clinically functioning gonadotroph adenomas, while rare, pose a diagnostic challenge and require careful clinical evaluation.

Transsphenoidal surgery is the mainstay of treatment of functioning gonadotroph adenomas, with the involvement of a multidisciplinary team to achieve desirable outcomes.

Published: March 2024

Aim: This study was aimed to investigate the effect of different hen ages on egg quality characteristics, hatching performance and chick quality in chukar partridges.

Materials and Methods: A total of 510 eggs obtained from chukar partridge flocks were used to determine the effects of different hen age on hatching performance, egg quality traits and chick quality. Daily collected 20 eggs from each age group (1, 2 and 3 years of age) were assessed for internal quality characteristics. A total of 150 eggs per each age group were set into incubator and hatcher set. After hatching, unhatched eggs were broken to determine hatching performance and embryonic mortality. Hatched day-old chicks were scored to determine chick quality characteristics.

Results: Internal egg quality traits were not statistically affected by different breeding ages. Different breeding ages did not affect hatchability, early and middle embryonic mortality while late embryonic mortality and fertility of eggs were statistically affected. The evaluated chick quality traits were affected by the different hen age.

Conclusion: Despite decreasing fertility rate with age, the results of this study suggest incubating eggs of chukar hens with 3 years age for optimum chick quality and being raised chukar hens up to 3 years of age.

The curliness of fibres and he degree of microcompression in the fibre wall strongly influence the properties of pulp suspensions, wet-webs, and dry sheets. In mill operation, curl and microcompression can be induced accidentally or intentionally, by shearing at high consistency. Some pulps are highly susceptible to curling; others are more resistant. Curl is not necessarily stable; it is readily removed from some pulps but not from others. Curl can be stabilized by certain treatments, notably by heat treatment at high consistency. This can be deliberate, or it can occur accidentally during mill operation, when a pulp is stored at an elevated temperature. Both curl and microcompression are often disregarded because they cannot be easily measured. Yet in practice their effects often dominate the properties of pulp suspensions, wet webs, and dry sheets. Ignoring these effects has led to costly surprises both in research and mill operation. In this paper the literature is reviewed and new data are introduced, illustrating the importance of curl and microcompression for mechanical, chemi-mechanical, and chemical pulps.

Directions and Results of Punctuation Management
Authors: Drukteinis Albinas
Published: March 2024

The article discussed the development of the basics and principles of punctuation in the descriptions of the management of punctuation. The mentioned bases for punctuation—grammar (syntax), meaning, and intonation and pauses—are proposed to be consolidated into two, grammatical (syntactic) and meaning- and intonation-based punctuation, regarding intonation as one of the ways of realizing the meaning of the text. The intonational basis is auxiliary in the realization of the general meaning of the text. It is appropriate to interpret these two bases as criteria for punctuation practice and rule development, and to consider the functionality of the punctuation marks and rules to be the general principle. For specific cases of interpretation of punctuation of syntactic units, the grammatical (syntactic) basis is important.Over the period of 100 years, the regulation of punctuation has largely adhered to a combination of grammatical (syntactic) and meaning- and intonation-based reasoning, only in isolated periods was there a greater tendency toward a more formal syntactic description of punctuation. In the recent period, more and more priority is given to the preferences of the author of the text, if it is necessary for the general meaning of the text.In recent decades, the phenomenon of incomplete, undeveloped or contracted (compressed) structures, which has come increasingly into focus in the descriptions of punctuation, can help to clarify problematic cases of punctuation of altered structures and more accurately define the possibilities of using punctuation marks. Punctuation rulescan be made more functional by breaking down syntactic phenomena in more detail and adding previouslyunexplored syntactic units to the rules.

Authors: E Gans Richard , Rutherford Kimberly , Alessandro Allisson D’
Published: March 2024

It is well established that complaints of dizziness, vertigo, unsteadiness, and internalized motion are commonly reported by patients to health care providers. It is estimated that dizziness is the 3rd most common complaint heard in physicians’ offices across all age groups, preceded only by headache and lower back pain. It has been observed by clinicians for over 100 years, that there is a sizable segment of this population of patients with or without a precedent vertigo episode who report difficulty coping and ambulating comfortably within a visually dynamic world. The purpose of this article is to provide the reader with an understanding of these conditions. This will include definitions of the conditions and a review of their symptoms and management options. The authors will provide a case study to highlight the complex nature of these conditions and successful management approach utilizing Vestibular Rehabilitation Therapy.
Meteorological Data and Spectral Analyses of Non-Equilibrium Processes in Water during the Total Solar Eclipse of 11.08.1999 in Bulgaria

Published: March 2024

There are partial or total solar eclipses every year on our planet. They are observed from relatively small areas. From 1950 to 2100, three total solar eclipses fell within the territory of Bulgaria. The two solar eclipses from the 20th century were observed on 15.02.1961 and 11.08.1999. The next total solar eclipse will happen on 3.09.2081. The partial solar eclipses in Bulgaria were on 3.10.2005, 29.03.2006, 1.09.2008, 4.01.2011, and 25.10.2022. The question of the influence of solar eclipses on the Earth’s atmosphere, water, and living organisms is an area of interest for many researchers. In this connection, studies have been conducted on atmospheric and water parameters during partial and total solar eclipses. Most investigations were performed with meteorological data – temperature and humidity. In the last 30 years, other methods have also been applied for the investigations of solar eclipses – spectral methods with infrared (IR) spectroscopy, studies of magnetic and electric fields, polarization, and measurements of the parameters of the fluids in plants. Our studies have used meteorological methods and analyses. For the effects on the water, spectral methods are applied to the non-equilibrium energy spectrum (NES) and differential non-equilibrium spectrum (DNES). A deionized water sample examined during the solar eclipse on 11.08.1999 was used, aiming to analyze the parameters of NES and DNES. The deionized water control sample was tested on 10.08.1999 at the same time as the solar eclipse of the next day. The results of our research show relatively rapid and significant changes in air parameters during a solar eclipse, which are most prominent immediately after its culmination. The conditions of non-equilibrium arising during the solar eclipse allow for studying the restructuring of the hydrogen bonds of water molecules. The results of the current studies prove that the solar eclipse’s significantly affect water which is the primary substance in the Nature and living organisms. These data are consistent with other ones which also prove that, during a solar eclipse, the structure of water undergoes significant changes. By influencing the water, this natural phenomenon affects the whole Nature and all living organisms on the planet.
A Communication and Decision-Making Framework for Pediatric Precision Medicine
Authors: Greene Brittany L. , Rosenberg Abby R. , Marron Jonathan M.
Published: March 2024

Advances in genomic testing have been pivotal in moving childhood cancer care forward, with genomic testing now a standard diagnostic tool for many children, adolescents, and young adults with cancer. Beyond oncology, the role of genomic testing in pediatric research and clinical care is growing, including for children with developmental differences, cardiac abnormalities, and epilepsy. Despite more standard use in their patients, pediatricians have limited guidance on how to communicate this complex information or how to engage parents in decisions related to precision medicine. Drawing from empirical work in pediatric informed consent and existing models of shared decision-making, we use pediatric precision cancer medicine as a case study to propose a conceptual framework to approach communication and decision-making about genomic testing in pediatrics. The framework relies on identifying the type of genomic testing, its intended role, and its anticipated implications to inform the scope of information delivered and the parents’ role in decision-making (leading to shared decision-making along a continuum from clinician-guided to parent-guided). This type of framework rests on practices known to be standard in other complex decision-making but also integrates unique features of genomic testing and precision medicine. With the increasing prominence of genomics and precision medicine in pediatrics, with our communication and decision-making framework, we aim to guide clinicians to better support their pediatric patients and their parents in making informed, goal-concordant decisions throughout their care trajectory.
La construcción desigual de la experiencia estudiantil en jóvenes universitarios del sur de conurbano bonaerense

Diversos estudios dan cuenta de que la masificación observada en las universidades durante las últimas dos décadas se produce con la incorporación de una población estudiantil que es, en su mayoría, primera generación de universitarios/as en sus familias. Estas investigaciones muestran que, en el caso de los sectores más desfavorecidos, la inclusión de las y los jóvenes al sistema educativo se produce a partir de una acumulación de desventajas en las condiciones educativas y sociales. La investigación que enmarca este escrito se propuso com- prender la compleja trama que configura la experiencia estudiantil en las y los jóvenes de ingreso reciente a las universidades del sur del conurbano bonaerense, identificando las dimensiones que definen, promueven u obstaculizan los logros académicos y la permanencia en las universidades. En este marco, se propone describir e interpretar las trayectorias escolares, las prácticas culturales que for- man parte de su vida cotidiana y social, las prácticas mediáticas y tecnológicas de acceso al conocimiento, sus experiencias como estudiantes de reciente in- greso, las expectativas sobre su futuro más inmediato académico y más mediato, profesional y/o laboral, entre otras. Para el desarrollo de la investigación se opta por una complementariedad metodológica, que articule técnicas y estrategias de investigación cuantitativa y cualitativa.

Este estudio tiene como objetivos caracterizar las barreras comunicativas vivenciadas por estudiantes en situación de discapacidad y conocer la percepción de docentes sobre las barreras comunicativas que enfrentan estudiantes en situación de discapacidad en contextos universitarios. Para esto, el estudio cuenta con un diseño metodológico cualitativo. Se utilizó la técnica de entrevista semi-estructurada vía online, con un tamaño de muestra de 8 participantes en total, con igual cantidad de estudiantes en situación de discapacidad y docentes. Ambos grupos pertenecían a universidades ubicadas en la región Metropolitana. Se realizó un análisis temático de las entrevistas. Los resultados muestran que existen barreras comunicativas físicas, psicológicas, semánticas, administrativas y digitales que afectan su participación y aprendizaje en el ámbito universitario. Así también, se identificaron facilitadores para aminorar el impacto negativo que estas barreras tienen en el ámbito académico y social para los estudiantes universitarios en situación de discapacidad. Los resultados del estudio dan cuenta de la necesidad urgente de desarrollar facilitadores de la accesibilidad comunicativa en el contexto de la educación superior, de forma de promover la participación plena de las personas en situación de discapacidad.

El objeto de este estudio es la elaboración de un Modelo Procesual Piloto de Articulación (MPPA) entre la Enseñanza Media Técnico Profesional (EMTP), Técnico de Nivel Superior (TNS), y Formación Profesional de Pregrado (FP). Su desarrollo contempla la generación de mecanismos pertinentes que permitan implementar trayectorias formativas articuladas, respondiendo al reconocimiento de los aprendizajes en las distintas áreas y niveles formativos, en el Marco de Cualificaciones Técnico Profesional(MCTP). La metodología utilizada es el “método de la ruta crítica” que identifica diversas acciones claves en un tiempo determinado. A partir de la identificación de éstas, se definieron 04 fases concatenadas que constituyen el MPPA, estableciéndose mecanismos, protocolos y procedimientos que fueron validados, los que forman parte de una batería de instrumentos para el reconocimiento de aprendizajes y trayectorias formativas de los estudiantes. Los resultados preliminares respecto al MPPA, denotan pertinencia de los mecanismos y protocolos utilizados para el reconocimiento de las trayectorias formativas.

Multi-year droughts are ever-present and transformational features of California’s Mediterranean climate and can fundamentally affect the water quality and the ecosystem responses of the San Francisco Estuary (estuary) and the Sacramento-San Joaquin Delta (Delta). This study assessed data collected by long-term monitoring programs over the past 46 water years (1975-2021) to evaluate how water quality in the estuary changes during multi-year droughts. Data were aggregated by region (South-Central Delta, North Delta, Confluence, Suisun Bay, and Suisun Marsh) and season, then differences between multi-year Drought periods, multi-year Wet periods, and Neutral periods were compared using generalized linear models. We found that multi-year Drought periods altered multiple physical and chemical parameters in the estuary, increasing water temperature, salinity, water clarity, and nutrient levels. This trend was consistent across regions and seasons, with few exceptions. Increases in these parameters during Drought periods were likely caused by reduced Delta inflows that intensified in each successive dry year because of reduced precipitation and managed estuarine inflows and outflows. Drought periods did not substantially affect tidal velocities within the estuary, which remained mostly consistent across Wet and Drought periods. Trends in chlorophyll concentrations during Drought periods were more nuanced with higher concentrations occurring in the South-Central Delta region and during the winter and spring. Together, these results characterized drought in the estuary as warm, clear, high in nutrients, with patchy phytoplankton blooms (as indexed by chlorophyll), all of which have implications for higher trophic levels. Considering that droughts are expected to increase in frequency and intensity in California with climate change, understanding the effects of multi-year droughts on the water quality conditions of the estuary can help inform water management decisions.
