The Transformation of a Person’s Life Plans in Mature Age
Authors: Shcherbakova T. N. , Inozemtseva O. M.
Published: March 2024

Introduction. There is a dual view about the orientation of transformation of life plans in people of mature age: on the one hand, the personality goes beyond the old structures, revealing its potential for the sake of further development; on the other hand, there is the risk of a motivational crisis associated with a change in the trajectory of personality development. Our research is designed to deepen and concretize ideas about the orientation and motivation of human life plans’ transformation at different stages of maturity. Purpose. The study of the peculiarities of motivation for the life plans’ transformation in mature age.

Materials and methods. In this study, 4 tests were applied: The Diagnostics of Motivational Structure of Personality test by V. E. Milman, the Index of Aspirations test by E. Desi and R. Ryan (adapted by Yu. A. Kotelnikova), the Morphological Test of Life Values (MTLV) by V. F. Sopov, L. V. Karpushina, Test for Assessing the Life and Time Prospects of a Person by N. I. Nikolskaya. The Mann-Whitney U-test was used for statistical analysis of the obtained data.

Results. The study involved 160 people aged 35–55. We found out that respondents’ motivational priorities differ in general orientation – representatives of early maturity are oriented externally, whereas the motivational orientation of older respondents is rather internal. The features of emotional experiences are also revealed: in early maturity, they are sthenic and characterized by productivity, and in later maturity, they are rather asthenic, hindering activity.

Discussion. Our study expands existing information about the motivational and emotional aspects of the life plans’ transformation in early and late maturity. The motivational priorities of the representatives of both age cohorts are established. In general, maturity is associated with a redefinition of the activity vector, a revision of the significance of life goals, and a transformation of plans, which leads to an expansion or change in the boundaries of the subject or the actualization of asthenic emotional experiences.
Features of Assertiveness of Boys and Girls with Different Coping Strategies
Authors: Kolchik E. Yu.
Published: March 2024

Introduction. The relevance of identifying the features of assertive behavior of modern young people with various coping strategies in modern society lies in effective interpersonal interaction with society. A review of research on this issue has shown that assertive behavior is a “mature” behavior aimed at countering manipulative behavior. Coping strategies in the framework of theoretical analysis seem to be an important element of assertive behavior. Purpose. To identify the features of assertive behavior of boys and girls with different coping strategies.

Materials and Methods. In this study, methods such as analysis of scientific literature, observation, conversation, the use of standardized techniques (methods for diagnosing the level of assertiveness by V. Kaponi and T. Novak, methods for diagnosing personal aggressiveness and conflict by E. P. Ilyin and P. A. Kovalev) and methods of statistical data processing (descriptive statistics and the Kruskal-Wallace mathematical criterion) were used.

Results. A theoretical research model has been developed, according to which assertive behavior includes cognitivesemantic, affective and behavioral components that explain in detail the features of personality interaction with society through assertive and coping behavior. The sample was divided into three groups according to the criterion of the predominant type of coping. As a result of statistical data processing, it was revealed that the level of assertiveness of respondents focused on finding social support is situational. Respondents using problem-solving strategies are characterized by a high level of assertiveness, while respondents focused on avoiding the problem have an average level of assertiveness.

Discussion. The assertive behavior of young people as self-affirming behavior is interrelated with the strategies of coping behavior used. The results of the study showed that coping strategies of various orientations are typical for people with different levels of assertiveness. This indicates the high practical significance of the results obtained in any practical activity aimed at adapting a person to society
The Relationship of Functional Roles and their Psychological Predictors in Solving Motor Tasks in Joint Mental Activity
Authors: Belousova A. K. , Kachan Ju. M.
Published: March 2024

Introduction. Modern society demands from young professionals non-standard ways of solving various tasks in a team. Despite the high interest in the problem of joint thinking, there is an insufficient number of comprehensive studies of psychological predictors involved in the formation of functional roles of participants in joint mental activity. Purpose. Analysis of the relationship between functional roles and their psychological predictors in solving motor tasks in joint mental activity.

Materials and methods. The study involved 208 people: they are students of humanities and technical specialties of the Southern Federal University aged 17 to 21 years. The task groups consisted of four subjects. For the solution, a motor task was used under the conditional name “Blocks”. To collect the data, the following methods were used: Kettell’s 16-factor personality questionnaire; a method for determining coping behavior in stressful situations; the “Personality orientation” method; Ehlers’ motivation for avoiding failures; Ehlers’ motivation for success; SELF-assessment; diagnosis of verbal creativity; heuristic competence test; a questionnaire for determining action control; the questionnaire “Methodology of assessment by participants of subgroups of partners from the point of view of their performance of functions of selforganization of joint mental activity”. The Pearson correlation coefficient is applied.

Results. The generation function is the least pronounced, which indicates a weak activity of carriers of this functional role in solving a motor-type problem. The function of semantic transmission is most pronounced, which indicates a focus on coordinating the goals of participants in mental activity to achieve a common result in solving a motor task, rather than on putting forward new hypotheses.

Discussion. Analyzing the distribution of roles, their functional content, it becomes possible to directly see the implementation of the features of mental activity carried out jointly, to assess the structure of intellectual activity of cognitive interaction of group members, to better understand the procedural features of joint mental activity. The interrelation of the personal characteristics of the participants in solving problems with the functional role distribution in joint thinking is emphasized, as well as the need for a comprehensive study of the acceptance and embodiment of roles by group members.
Negative Phrases can Cause a Negative Emotional Assessment: an Empirical Study
Authors: Andreeva G. A.
Published: March 2024

Introduction. There are theoretical propositions declaring that negations carry a negative emotional charge. Indirectly, this is confirmed by a number of modern studies. However, it remains unknown whether negations in their most abstract lexical form are capable of causing a negative emotional effect. In the presented study, the negative effect of denial was revealed for the first time. Purpose. Theoretically substantiate the emotional negative effect of negations and empirically identify it by comparing evaluations of negative and affirmative phrases.

Materials and methods. In studies related to the topic, it is difficult to differentiate the influence on the emotional assessment of the meaning of the negated concept from the influence of the negative form itself. To identify the negative emotional effect of lexical negations, we asked subjects to evaluate affirmative and negative phrases not only with a pronounced emotional meaning, but also with a neutral one, which allowed us to minimize the influence of the meaning of the phrase. The study involved 87 subjects who rated phrases using two methods: R. Likert’s direct scale assessment and color-mediated assessment (A. M. Etkind’s RCT method).

Results. The results showed a high significance of the differences between the negation of the neutral and the assertion of the neutral, negative phrases were indeed evaluated more negatively. An additional comparison of phrases with emotional meaning showed that denial softens the emotional expression of the concept, shifting its assessment closer to the neutral part of the scale.

Discussion. Previous studies have shown a connection between a negative response and negative emotional reactions. In our study, it was shown for the first time that even an abstract version of a negative phrase can significantly shift an assessment into the negative spectrum of the emotional scale. These data are consistent with the embodied approach to language analysis, where sensorimotor and emotional reactions underlie the formation of abstract language forms. For the first time, the revealed connection between lexical negation and negative emotional reactions deepens the understanding of one of the most frequent linguistic means.

Authors: Gjerazi Blerina
Published: March 2024

This study examines the profound impact of media on shaping public perceptions of brain drain, a globally significant issue with far-reaching implications for politics, society, and the economy, particularly in developing countries such as Albania. Focusing specifically on skilled professionals’ migration in pursuit of enhanced opportunities, the research scrutinizes how media influences their decisions to emigrate, analyzing news coverage and perspectives on migration as factors influencing economic status and quality of life.

Against the backdrop of a burgeoning body of scholarly research highlighting the media’s substantial influence on public perceptions and attitudes toward migration, this study contributes by delving into the intricate relationship between media narratives and brain drain perceptions. It examines news coverage and occupation trends, paying special attention to potential stereotypes reinforcing the dichotomy of “skilled leaving” versus “unskilled staying.” The analytical framework integrates concepts from framing, agenda-setting, social constructivism, and critical discourse on globalization perspectives.Empirical data have been collected from a comprehensive sample of 50 Albanian news articles specifically related to brain drain. The synthesis of theoretical approaches and existing scientific studies in this domain complements the data collection. The findings shed light on the media’s capacity to shape perceptions of migration, particularly its influence on professions and quality standards. The study emphasizes the imperative of balanced and objective framing in media discourse to mitigate biases against professionals opting to remain in their home countries. Anticipated contributions include nuanced insights into the complex relationship between media, brain drain, and public perceptions, adding depth to the existing literature.
Ve, vívelo y cuéntalo. Los aportes del enfoque etnográfico para un periodismo de calidad

Published: March 2024

Gabriel García Márquez resumía el trabajo periodístico con tres verbos: ve, vívelo y cuéntalo (Gayà Morlà, 2015). En estas tres acciones, pilares del slow journalism que impulsa la Fundación Gabo, se formula una manera de entender el periodismo alejado de la visión positivista, que asume que el relato periodístico es “una mediación cultural de naturaleza simbólica e interpretativa” (Vidal Castell, 2000) y que tiene como función organizar nuestra relación con el mundo en común. En las siguientes páginas y desde las aportaciones de la Escuela de Bellaterra (Garde Cano, 2022), se demuestra que el periodismo impulsado por la Fundación incorpora de facto el enfoque etnográfico, que aporta una calidad distintiva y debe considerarse, no solo un método, sino una metodología. Así, se argumenta que un periodismo de calidad integra per se una epistemología etnográfica: es decir, una metodología reflexiva que ayuda a entrenar la mirada y deconstruir privilegios; y un método inmersivo como única forma de comprender para narrar a partir de la sensibilidad y la imaginación. En el apartado de metodología se presenta una guía que permite identificar y analizar las señas etnográficas de un texto periodístico de calidad. Esta guía se pone a prueba en tres reportajes, ganadores del premio Fundación Gabo.

Published: March 2024

This research aims to improve basic locomotor movement skills in grade 5 elementary school students through active learning interventions based on traditional games. In this research, researchers used a quasi-experimental research design with stratified random sampling. Two groups of students were selected, where one group was given active learning intervention, while the other group was a control group that received conventional learning. The research instruments used included basic movement skills tests, student response questionnaires, participant observation, and field notes. The collected data was analyzed using descriptive statistical methods and the T test to compare the differences between the two groups before and after the learning intervention. The statistical calculation method used was the T test, which was used to compare the differences between the experimental group and the control group in terms of improvement in basic locomotor movement skills after the intervention. By using the T test, researchers can evaluate whether there are significant differences between the two groups and whether traditional game-based active learning interventions are effective in improving the basic movement skills of grade 5 elementary school students. The research results show that traditional game-based active learning interventions have a significant positive impact in improving basic locomotor movement skills in grade 5 students. This shows the important potential of interactive and fun learning methods in improving the quality of learning and the development of students' motor skills. In conclusion, active learning interventions based on traditional games can be effective in improving basic locomotor movement skills in grade 5 elementary school students. This research provides important implications for the development of a more inclusive and student-centered curriculum at the elementary school level.

Authors: Dey Anindita , Guha Subhanil , Govil Himanshu
Published: March 2024

Soil hazard zonation in watershed is quite significant to take the necessary actions for soil conservation. The present study attempts to identify soil hazard zones for proper soil conservation and prepare a treatment plan for the Bandu sub-watershed of India through morphometric analysis techniques by giving rank based on priority. The result of the prioritization of eighteen micro-watersheds is entirely satisfactory due to the use of fourteen morphometric parameters. The study quantifies the potential soil loss and identifies the soil eroded zone of the sub-watershed using the universal soil loss equation method and the entire region is categorized into three soil hazard zones with varying degrees. Indian Remote Sensing Satellite data have been used to conduct the whole study. The micro-watershed prioritization has been estimated by applying the composite morphometric value. The micro-watershed having 5.625 composite value ranks first for prioritization (most vulnerable with maximum soil erosion) and having 15.875 composite value ranks last for prioritization (least vulnerable with minimum soil erosion). The result also shows that the soil loss ranges from 0-30 tonne/hectare/year with an average soil loss of 0-10 tonne/hectare/year in maximum areas of the sub-watershed. The soil loss map shows that along the Bandu and in some agricultural fields, the central part of the region is susceptible to soil erosion. The scientific approach of this research could be more effective in maintaining sustainable rural planning. The study can be used as a reference work for determining soil hazard zones in any tropical watershed with high soil loss risk.
Sites of Memory in Czechoslovak Silesia 1945–1948
Authors: Kolář Ondřej
Published: March 2024

The paper aims to describe and analyze the changes in public sites of memory in the multi-ethnic border region of Czechoslovak Silesia during the period of restoration of Czechoslovak sovereignty, between the fall of Nazism in May 1945 and the communist putsch in Czechoslovakia in February 1948. This research focuses on transformations and (dis)continuity of cults and symbols during that period, and on specifics and differences within the examined region with regard to ethnic and social structure of local population. Research is based primarily on the recorded agendas of state and district administrations, but preserved memorials and photographs or descriptions of vanished sites of memory also serve as important sources.

After the expulsion of German population, the western part of the region was repopulated by settlers from various regions of East-Central Europe. Most of local German sites of memory vanished, with the partial exception of religious symbols and a few “apolitical” memorials. New monuments and memorials were dedicated mainly to personalities of Czech history in an effort to inculcate the “official” identity amongst the new-settlers.

In the Ostrava coal basin, the new regime invoked the pre-war tradition of working-class identity and showed tolerance towards the sites of memory of the local Polish minority, except memorials related to the former Czech-Polish border conflicts. In the Hlučín region specifically, a strong pro-German narrative survived despite the “Czechization” efforts of state authorities.

In general, the state-supported memory policy aimed to create the narrative of a “Slavic” and “socialist” Silesia, suppress the German past of the region, and weaken frictions between Czechs and Poles.

Published: March 2024

The study aimed to determine the magnitude of changes in air temperature in Skierniewice, Poland, over the last 100 years, with particular emphasis on multi-year variability. The source material for the analyses were air temperature measurements from 1923 to 2022 obtained from the meteorological station in the Experimental Field of the Warsaw University of Life Sciences and the station in the Experimental Orchard of the National Institute of Horticultural Research. The study presents average annual, minimum, and maximum air temperatures along with an assessment of the trend of their multi-year variability. The features of changes in the average air temperature in Skierniewice presented in the study based on a 100-year series of meteorological measurements are characterized by high temporal variability with a clear upward trend. The average warming rate over 100 years was 0.17 °C per 10 years, but in the last 60 years it has already reached 0.38 °C per 10 years. In the case of the average annual air temperature since 1981, there has been a sequence of years warmer than average throughout the measurement period. The number of summer days (>25 °C) and hot days, when the maximum temperature exceeds 30 °C, is also increasing. In the analyzed period, the decade 2013–2022 was the warmest.
Enhanced Bird Swarm Algorithm with Deep Learning based Electroencephalography Signal Analysis for Emotion Recognition
Authors: Al-Farouni Mohammed H.
Published: March 2024

Bioelectric signals comprise a massive count of data, and researchers in various domains containing cognitive neuroscience, psychiatry, and so on. Emotion is a vital part of regular human communication. The emotional conditions and dynamics of brain are connected by electroencephalography (EEG) signal which is utilized by Brain-Computer Interface (BCI), for providing optimum human-machine interaction. EEG-based emotion detection was extremely utilized in military, human-computer interactions, medicinal analysis, and other domains. Identifying emotions utilizing biological brain signals need accurate and effectual signal processing and extracting features approaches. But, one of the essential problems facing the emotion detection method, utilizing EEG signal is the detection accuracy. In this aspect, this study develops an Enhanced Bird Swarm Algorithm with Deep Learning based Electroencephalography Signal Analysis for Emotion Recognition (EBSADL-ESEG) technique. The ultimate aim of the EBSADL-ESEG technique lies in the recognition of emotions using the EEG signals accurately. To perform this, the EBSADL-ESEG technique initially extracts the statistical features from the EEG signals. In addition, the EBSA technique is employed for optimal feature selection process. Moreover, the gated recurrent unit (GRU) with root mean square propagation (RMSProp) optimizer is utilized for classifying distinct emotions (arousal, valence, and liking). The experimental analysis of the EBSADL-ESEG model is tested on DEAP dataset and the outcomes are investigated under diverse measures. The comprehensive comparison study revealed better outcomes of the EBSADL-ESEG model over other DL models.

Handwriting Recognition (HWR) is a difficult and varied discipline having applications in a wide range of fields, including banking, education, and administration. This research investigates the two main types of HWR systems: online and offline character recognition. Online HWR entails real-time input utilizing digital pens to capture dynamic handwriting traits. It’s used in contemporary gadgets like tablet computers and for signature verification. Offline HWR, on the other hand, processes scanned documents, making it important in situations such as bank cheque processing and assisting the visually handicapped. The research emphasizes the continuing potential for progress in HWR, notably using machine learning and deep learning approaches. Machine learning, a subset of Artificial Intelligence (AI), is critical in developing character recognition algorithms. The selection of an effective classification model is a vital decision, and the study uses a specific dataset to conduct a comparison analysis of alternative models to help in this process. Such assessments provide useful insights for academics and practitioners, allowing them to make more informed judgements on model development for HWR applications.
Optimal Deep Learning Driven Smart Sugarcane Crop Monitoring on Remote Sensing Images
Authors: Shakir Ahmed Kareem
Published: March 2024

Crop monitoring is a process that involves regular field visits that seem to be difficult since it needs a huge amount of time and manpower. Thus, in modern agriculture, with an extensive range of satellite data such as Landsat, Sentinel-2, Modis, and Palsar, data are readily available. Sugarcane is a tall perennial grass belonging to the genus Saccharum, utilized for producing sugar. These plants were generally 2–6 m tall with fibrous, stout, jointed stalks, rich in sucrose, that will be accumulated in the stalk internodes. Sugarcanes have a different growth pattern and phenology than many other crops; thus, the spectral and temporal features of satellite data are examined by utilizing statistical and machine learning (ML) techniques for optimal discrimination of sugarcane fields with other crops. In this study, we propose an Optimal Deep Learning Driven Smart Sugarcane Crop Monitoring (ODLD-SSCM) model on Remote Sensing Images. The presented ODLD-SSCM model mainly intends to estimate the crop yield of sugarcanes using RSIs. In the presented ODLD-SSCM technique, the sugarcane yield mapping can be derived by the use of the self-attentive deep learning (SADL) model. Besides, an oppositional spider colony optimization (OSCO) algorithm is used for the hyperparameter tuning of the ODLD-SSCM model. A detailed set of experimentations were performed to demonstrate the enhanced outcomes of the ODLDSSCM model. A comprehensive comparison study pointed out the enhancements of the ODLD-SSCM model over other recent approaches.
Web Technology Grounded Effects of Task Scheduling in Distributed and Cloud Systems

Published: March 2024

One definition of the word “distributed system” describes it as “a set of entities that collaborate in order to find a solution to a problem that cannot be solved by a single entity using their own resources.” This description of a distributed system is an example of a distributed system. As the number of algorithms that are mathematically complicated continues to increase, distributed computing systems have emerged as a direct result of this trend. The optimization of a distributed computing system has been accomplished via the development of methods for the distribution of work and the scheduling of jobs. Because of this, the system has been able to be used in a more efficient manner. Task scheduling refers to the process of selecting the order in which actions are carried out in response to a given set of circumstances. On the other hand, task allocation is the process of allocating tasks to the processors in a system that are the most fit for taking on those tasks. This procedure determines which processors are assigned the jobs. Within the context of distributed systems, the objective of this article is to provide a detailed review of the several approaches to task scheduling that have been used by researchers.

Authors: Tang Bo , Yang Jiangen , Chen Wei , Ming Xu
Published: March 2024

A steady-state sinusoidal and distortion-free excitation source is very important for the accuracy and consistency of the calibration parameters of micro-electro-mechanical systems (MEMS) inertial sensors. To solve the problem that the current MEMS inertial measurement unit (IMU) calibration device is unable to reproduce the spatial motion of linear and angular vibration coupling, research topics on the coupling vibration characteristics and parameter identification for an electromagnetic linear-angular vibration exciter are proposed. This research paper used Ampere’s law and Lorentz force to establish the analytical expressions for the electromagnetic force and electromagnetic torque of the electromagnetic linear-angular vibration exciter. Then, the main purpose of this paper is to establish uniaxial and coupled vibration electromechanical analogy models containing mechanical parameters based on the admittance-type electromechanical analogy principle, and the parameter identification model is also obtained by combining the impedance formula with the additional mass method. Finally, the validity of the coupling vibration characteristics and the parameter identification model are verified by the frequency response simulation and the additional mass method, and the relative error of each parameter identification is within 5% in this paper.
Impact of early integrated rehabilitation on fatigue in 600 patients with breast cancer – a prospective study
Authors: Auprih Masa , Zagar Tina , Kovacevic Nina , Smrdel Andreja Cirila Skufca , Besic Nikola , Homar Vesna
Published: March 2024

Background

Fatigue after breast cancer treatment is a common burden that is challenging to treat. The aim of this study was to explore if such integrated rehabilitation program reduces the prevalence of chronic fatigue compared to simple, non-integrated rehabilitation.

Patients and methods

The subjects of our prospective study were 600 female breast cancer patients (29–65 [mean 52 years] of age), who participated in the pilot study on the individualized integrated rehabilitation of breast cancer patients in 2019–2021 and were monitored for one year. The control group included 301 patients and the intervention group numbered 299 patients. The patients completed three questionnaires (EORTC QLQ-C30, -BR23 and NCCN): before cancer treatment, and then six and twelve months after the beginning of cancer treatment. The control group obtained the standard rehabilitation program, while the intervention group was part of the early, individualized multidisciplinary and integrated approach of rehabilitation. The rehabilitation coordinator referred patients for additional interventions (e.g., psychologist, gynecologist, pain management team, physiotherapy, clinical nutrition team, kinesiologist-guided online training, vocational rehabilitation, general practitioner). Data on the patients’ demographics, disease extent, cancer treatment and complaints reported in questionnaires were collected and analyzed.

Results

There were no differences between the control and the intervention group of patients in terms of age, education, disease extent, surgical procedures, systemic cancer treatment, or radiotherapy, and also no differences in the fatigue before the beginning of treatment. However, patients from the control group had a greater level of constant fatigue than patients from the intervention group half a year (p = 0.018) and a year (p = 0.001) after the beginning of treatment. Furthermore, a greater proportion of patients from the control group experienced significant interference with their usual activities from fatigue than from the intervention group, half a year (p = 0.042) and a year (p = 0.001) after the beginning of treatment. A multivariate logistic regression showed that one year after the beginning of treatment, the only independent factor correlated to fatigue was inclusion into the intervention group (p = 0.044). Inclusion in the intervention group was beneficial—patients from the control group were 1.5 times more likely to be fatigued.

Conclusions

Early individualized integrated rehabilitation is associated with a lower prevalence of chronic fatigue or fatigue interfering with usual activities in breast cancer patients in comparison to the control group of patients.

Published: March 2024

Background

Craniospinal irradiation (CSI) poses a challenge to treatment planning due to the large target, field junction, and multiple organs at risk (OARs) involved. The aim of this study was to evaluate the performance of knowledge-based planning (KBP) in CSI by comparing original manual plans (MP), KBP RapidPlan initial plans (RPI), and KBP RapidPlan final plans (RPF), which received further re-optimization to meet the dose constraints.

Patients and methods

Dose distributions in the target were evaluated in terms of coverage, mean dose, conformity index (CI), and homogeneity index (HI). The dosimetric results of OARs, planning time, and monitor unit (MU) were evaluated.

Results

All MP and RPF plans met the plan goals, and 89.36% of RPI plans met the plan goals. The Wilcoxon tests showed comparable target coverage, CI, and HI for the MP and RPF groups; however, worst plan quality was demonstrated in the RPI plans than in MP and RPF. For the OARs, RPF and RPI groups had better dosimetric results than the MP group (P < 0.05 for optic nerves, eyes, parotid glands, and heart). The planning time was significantly reduced by the KBP from an average of 677.80 min in MP to 227.66 min (P < 0.05) and 307.76 min (P < 0.05) in RPI, and RPF, respectively. MU was not significantly different between these three groups.

Conclusions

The KBP can significantly reduce planning time in CSI. Manual re-optimization after the initial KBP is recommended to enhance the plan quality.
The Size of the Rental Housing Segment in Poland and its Main Determinants
Authors: Derkacz Arkadiusz J. , Cohen Viktorija
Published: March 2024

Our research into the fast-growing segment of the rental market fits perfectly with the current wave of excitement. In this research, we attempt to answer a fundamental question: how large is the rental segment in Poland? To our surprise, the answer to this key question remains wrapped in mystery, with an absence of continuous studies disclosing its true size.

Undaunted, in this paper we took up the challenge to develop a method that would give us a clear answer. Using Eurostat statistics, we develop a methodological framework for estimating the size of the rental segment. We acknowledge that Eurostat data possesses certain limitations, yet serves as a valuable resource for fulfilling our goal under the proposed methodology. In our approach, we determine the size of Polish rental segment between 2007 and 2021. To validate our findings, we dived into the complex relationship between the size of the rental segment and households. Applying linear regression, we sought to unravel the main determinants influencing not only the overall housing market but also the dimensions of the puzzling rental segment. The proposed method proves to be successful and answers the research question. However, it is important to emphasize that the presented results are estimates that give an impression of the elusive size of the rental housing segment and not exact measurements. Moreover, the flexibility of the proposed methodology is promising and allows similar studies to be conducted in different geographical contexts.
The Potential of Residential Property in Poland as an Inflation Hedge Investment
Authors: Dittmann Iwona
Published: March 2024

The research objective of the article was to assess the potential of residential property in Poland as an inflation hedge investment. The study was conducted using innovative measures of the level of inflation hedging. The study was made for Poland’s six largest local residential markets, for two types of investments, for different investment horizons (from 6 to 15 years). The research period adopted was: 3Q2006-4Q2022. In all cities, investments providing only capital gains allowed an attractive inflation hedging level to be achieved. Investments that additionally included rental offered a high inflation hedging level. The variation in the six cities studied in terms of inflation hedging through housing investment was found to be very low. The question of how extending the investment horizon affected the inflation hedging ability was not firmly answered. Frequently, the extension of the investment horizon has been accompanied by an increase in the level of hedging.

Published: March 2024

Tahi Ayam (Lantana camara Linn.) is known for its traditional medicinal purposes, can be used for treating various diseases. This is ascribed to the abundant presence of secondary metabolite compounds in Lantana camara Linn. In particular, the ethyl acetate extract of Lantana camara Linn. leaves contain secondary metabolite compounds belonging to the triterpenoid, steroid, coumarin, and phenolic groups. One of the triterpenoid compounds isolated from the ethyl acetate extract of Lantana camara Linn. leaves are 9-hydroxy-Lantadene A. Subsequently, an antibacterial test was conducted on this compound to assess its ability to inhibit the growth of test bacteria i.e. Staphylococcus aureus (Gram-positive) and Escherichia coli (Gramnegative). Amoxicillin was employed as a positive control. In addition to testing the antibacterial properties of the 9-hydroxy-Lantadene A compound, the ethyl acetate fraction of Lantana camara Linn. leaves also underwent the same antibacterial testing procedure. The results of this study suggest that both the isolated compound and the ethyl acetate fraction from Lantana camara Linn. leaves possess antibacterial activity. However, it's important to note that the antibacterial activity observed in both samples is relatively low. The possible cause of this could be the low sample concentrations utilized in the research

Purpose: The objective of this research is twofold: (1) to elucidate the progression of studies pertaining to the application of signaling theory in financial management, and (2) to scrutinize the bibliometric analysis of the implementation of signaling theory in financial management.
 
Method: The employed technique is clustering, overlay, and density of bibliometric analysis. The utilized tools include publishing platforms such as Publish or Perish, Google Scholar, and VosViewer. 
 
Results and Conclusion: The research findings indicate a limited amount of literature exploring the utilization of signaling theory in financial management. This is evident in the minimal growth in the number of papers published between 1994 and 2023, with an average of only 1 to 3 papers per year.
 
Research Implication: Concerning the primary keywords that commonly arise in this study, specifically "theory" and "signaling theory", there exist five clusters of keywords with the utmost frequency of occurrence. Applying signaling theory in financial management has been demonstrated to enhance investors' propensity to allocate their capital.
 
Originality/Value: The role of financial management is vital in determining the company's profitability. Implementing financial management using the signaling theory approach is a viable method to achieve profitability. The theory of signaling is instrumental in conveying signals to investors regarding the financial state of the company. The findings of this study can offer valuable understanding regarding the implementation of signaling theory in financial management, thereby serving as a basis for considering the utilization of this theory.
Gold in phosphorites: Accumulation forms and practical significance
Authors: Georgievskiy A. F. , Bugina V. M.
Published: March 2024

Research subject.The gold-bearing potential of modern (oceanic) and ancient industrial types of phosphorite ores, including aphanitic, microgranular, granular, nodular, shell and karst.Aim.To assess the ability of phosphorites to accumulate gold to industrial concentrations. This issue has been actively discussed in the geological community in recent years due to the advent of high-precision methods for studying matter.Methods.Russian and foreign publications, unpublished geological data, as well as the authors’ data collected over a 30-year period of studying phosphorites. Results and discussion. In the section, 14 packs of rocks were identified, which are represented by 6 lithological types of secondary dolomites. Their distribution along the section, along with the presence of characteristic faunal remains, made it possible to establish three members in the section, which can be correlated with the Katian, Hirnantian, and Ruddanian stages of the General Stratigraphic Scale.Conclusion.Conditions for the possible joint accumulation of phosphates and gold are manifested in black shale basins, as well as in shelf shallow waters with glauconite-sand sediments. However, due to significant differences in the natural features of gold and phosphates, their industrial clusters are formed separately from each other. This is evidenced by the insignificant accumulation of phosphorus in the ores of gold deposits of black shale formations,as well as its low-quality concentrations in industrial phosphorite beds of phosphorite-bearing basins. For gold, phosphorites are only temporary collectors, the productivity of which depends on the combination of many, frequently random and slightly related factors.
