Comparison of fatty acid composition of the eggs of wild and farmed Coregonus maraena and the influence of feed
Authors: Bochert Ralf , Bernolle Dominik , Grunow Bianka 
Published: June 2023

Abstract
The fatty acid (FA) compositions of eggs from wild whitefish and captive broodstocks were investigated to estimate the FA requirements of Coregonus maraena. The aim of this study was to increase basic knowledge on the nutritional needs of broodstock. Whitefish eggs from two natural spawning grounds were compared with that of captive broodstocks that were fed three commercially available feeds used in fish farms in Mecklenburg-Vorpommern, Germany. Wild fish eggs differed significantly in crude protein content and FA profiles from the eggs of experimentally farmed fish groups. The percentage of monounsaturated FAs (MUFA) were significantly lower in the wild fish eggs. The most common MUFA was oleic acid in all groups, although in the wild fish eggs the value of it was almost half of that in farmed fish eggs. Wild fish eggs had significantly higher values of total polyunsaturated FAs (PUFA), especially of n-3 PUFA, which was nearly double that of the eggs of the farmed fish groups. Additionally, it was shown that egg FA composition even differed between the wild fish stocks that were from the same area, whereas there were no differences in egg proximate composition or FA composition among the three feeding groups even though the compositions of the feeds fed to these fish differed significantly. The present study suggested that the proportions of essential FAs supplied in the dry feeds fed to the captive broodstocks were inappropriate for this species, and feeds must be adapted further to meet the nutritional requirements of this species to improve the quality of farmed whitefish eggs.
The Association Between Religiosity and Social Behaviour Among Children: A Romanian Perspective
Authors: Tudoran Marina Alexandra , Neagoe Alexandru 
Published: June 2023

Abstract
For children, a proper environment will support the development of pro-social characteristics, while a hostile environment is likely to lead to anti-social development. Starting from this premise, the main purpose of this work is to determine if and to what degree children’s involvement in Christian practices, acquired as a result of living in a Christian environment, is reflected in their socio-emotional development. This possible association was assessed using Spearman and Pearson correlations and simple linear regression on some religious attributes (as independent variables) and some positive and negative age-specific social manifestations (as dependent variables). The results of the study show that an increased level of religious behaviour could predict a higher chance of positive social behaviour outcomes. Thus, religiosity may be regarded as one possible good influence on children’s development in future adults.

Authors: Naga Saritha K. , Rao G. S. , Rosaiah K. 
Published: June 2023

Abstract
A new Lomax Rayleigh distribution (NLRD) is proposed and generated using Transformed Transformer (T-X) family generator. Various structural properties like generating functions, moments, limiting form, quantile function median and mode of NLRD are studied. Maximum likelihood estimators (MLEs) of the parameters are obtained and the model fitting is tested with simulated data. Model adequacy with live data is explained with two real-time cancer data sets. The NLRD shows a better fit in the estimation of survival in bile duct cancer and head and neck cancer data than other existing distributions.

Published: June 2023

Abstract
The space debris population is constantly increasing, including large spare upper stages and spacecraft. Atmospheric re-entry events caused by these artificial objects pose a threat to the ground-based population and their understanding and accurate modelling are required. On the 24th of October 2020, two cameras of the AMOS system in the Hawaiian Islands recorded the re-entry event of spare rocket’s upper stage. In the presented work, we aim to improve and automate the process of fragment identification between simultaneously acquired video recordings of this event. We are presenting the whole processing pipeline. First segmentation is performed to identify the cluster of interest and flying fragments within that cluster in all frames. The acquired information is used to create tracks of individual flying fragments – frame objects to be further associated between recordings.
Determinants of Firm-Level Growth: Lessons from the Czech Republic, Hungary, and Poland
Authors: Lee Mihye 
Published: June 2023

Abstract
This paper examines the determinants of firm-level growth based on three eastern European countries – the Czech Republic, Hungary, and Poland. We investigate whether there exist common firm-level characteristics that play a significant role in determining firm-level performance across the three countries, and whether development in financial markets can facilitate the growth of individual firms, particularly for firms that require external financing (borrowing). Our empirical analysis shows that in the case of Poland, firm-level characteristics, such as firm age and firm size, turn out to be significant, and that the role of these factors on the sales growth of firms is quite consistent with the findings in the existing literature. The same firm-level characteristics do not appear to be significant in the cases of Czechia and Hungary, which suggests that these factors play a different role in the firm-level growth of these countries. However, a firm’s access to external financing matters for the determining the firm’s growth and its development of financial markets, which enables the firm to have easier access to external sources of financing, thereby especially facilitating the growth of the individual firm that might need external funds. Our findings provide additional empirical evidence on the existing literature that emphasizes the positive impact of financial development on the individual firms’ growth based on a cross-country analysis.
Modelling National Economic System: A Case of the Croatian Economy
Authors: Sovilj Siniša , Tkalec Marina , Pripužić Dominik , Kostanjčar Zvonko 
Published: June 2023

Abstract
In this study we evaluate a national economic model using a system dynamics approach. We use a set of macroeconomic data for a transition economy to validate the model behaviour in the past, and then simulate the alternative paths of key macroeconomic variables. Instead of studying only a fraction of the economy, or using simple and abstract models, we build a large-scale national economic model. As the study is based on system dynamics information feedback, it provides additional insights about the macroeconomic effects of the economic policy, making it a valuable tool for economic policy analysis. Such insights are instrumental for understanding the total effects of economic policies and their full economic consequences. To demonstrate this, we have simulated one actual economic policy intervention and its alternative scenario.
Economic Consequences of the Cost of Government Borrowing in European Transition Economies
Authors: Havolli Berat 
Published: June 2023

Abstract
Given the need of transition economies to fund the investments necessary for development partly through borrowing, this paper investigates empirically the economic consequences of the government cost of borrowing for European transition economies during the period 2003-2016. The investigation analyses the impact of sovereign borrowing costs, in turn, on interest rates on loans to businesses and households, on the growth rates of investment and consumption, and, ultimately, on general economic activity. By utilizing a panel VAR technique our results indicate that consequent upon a positive shock to the cost of sovereign borrowing, the cost of borrowing for loans to both Non-Financial Corporations (NFCs) and households increases. We find that the price transmission from government borrowing costs to the private sector is at play with respect not only to borrowing rates but also to macroeconomic activity at large. Following an increase in sovereign borrowing costs, we observe substantial negative responses in the growth rates of investment, household consumption, and GDP growth. Also, while a price of borrowing increase for NFCs is found to negatively affect investment, household consumption is unaffected by an increase in household borrowing rates. These findings have valuable policy implications for policymakers and stakeholders in transition economies. Specifically, the results suggest that efforts to reduce the cost of sovereign borrowing could have a positive impact on the economy by lowering borrowing costs for households and businesses, promoting investment and consumption, and ultimately boosting economic growth.

Abstract
Ethiopia harbour the Eastern afromontane and Horn of Africa hotspots of biodiversity. The general objective of this study was to investigate the floristic composition and diversity of species, the structure and the regeneration status of the Hurubu forest. Three parallel transects lines with 1 km length were systematically laid across the forest with an interval of 500 m in south to north direction. Thirty sample quadrants of 20 m × 20 m were placed along transects at an interval of 200 m for mature trees and shrubs, while for the purpose of seedling and sapling inventory, four sub-quadrants of 1 m × 1 m were laid at each corner of the main quadrant. A total of 32 woody species representing 25 families were recorded consisting of trees and shrubs. The lower storey consisted of all woody plant species, except Ekebergia capensis tree species. The middle storey consisted about 14.41 % of the tree species while the upper storey involved only 2.35 % of the total individual trees in the forest. The total basal area of woody plants in Hurubu forest was 90 m2 per ha. The three most important woody species with the highest IVI were Juniperus procera, Osyris quadripartite and Myrsine africana in decreasing order. The general regeneration status of the tree species of the study site was satisfactory at the community level showing a ‘fair’ regeneration status. Therefore, special conservation actions should be implemented for the poorly and not regenerating woody species of the forest.
Observations of birds of prey in Eastern Nimba Nature Reserve, Liberia between 2015 and 2017
Authors: Prommer Mátyás 
Published: June 2023

Abstract
Distribution and biology of birds of prey species have been well-documented in most parts of the globe. Knowledge gaps are continuously shrinking due to more research, new technologies and increasing possibilities to reach remote areas. However, there are still some regions where data on birds of prey are scarce due to various reasons. Some parts of West Africa are such places, mostly because civil wars and the outbreak of Ebola prevented any kind of research. In the period 2015–2017, a butterfly research project in Nimba Mountains, Liberia offered opportunity to collect data also on birds of prey species. This article aims to provide a comprehensive list of birds of prey species in the area and compare it to other available historic and recent lists. In the frame of the project, 20 species were recorded. The results of comparing historic and recent records show that species of dry open habitats appeared and even settled in Nimba Mountains’ predominantly rainforest habitat. That suggests a habitat shift likely due to both climate change and human land transformation activities.

Published: June 2023

AbstractThe purpose of this study is to identify the knowledge of the real estate market by students and graduates and to find out their housing and investment plans. A literature study relating to the real estate market was conducted. The diagnostic survey method was used to determine the housing and investment plans of students and graduates, their expectations regarding changes in housing policy, and their level of knowledge of basic concepts and relationships related to the real estate market. The survey was conducted in March 2022 among students and graduates of Wroclaw University of Economics and Business. The great majority of the respondents consider the housing policy in Poland to need changes, mainly in the direction of greater support for young people, lowering the costs of mortgage loans and reducing the formalities associated with the construction of real estate. Moreover, research indicates that less than half of young people are able to fully support themselves during or shortly after graduation. Only one in four respondents had a disposable income of more than PLN 2,000. Many students and graduates plan to purchase real estate in the future, and nearly 60% of respondents intend to finance the purchase with a mortgage.
Exploring Language Anxiety Among Turkish Heritage Language Learners in Germany
Authors: Ergüt Selçuk Emre , Baş Bayram 
Published: June 2023

Summary
Heritage language speakers may feel anxiety about using their heritage language in different settings due to monolingual ideologies, family attitudes, language proficiency, and many other factors. However, the experience of those enrolling in heritage language classes has yet to be known in detail. This study examined heritage language anxiety (HLA) toward speaking skills among Turkish heritage language learners (HLLs). A descriptive design was used to seek the HLA level and its relations with various variables such as the home language, communicative language with friends, self-perceived proficiency, age, gender, grade level, birthplaces of children and parents, age of acquisition (AoA), book-reading and movie-watching languages. Three hundred and three school-age bilingual Turkish children in Germany participated in the study. The results demonstrated that the HLA level of the target group was low. In addition, in-class HLA was significantly higher than out-of-class. Moreover, HLA levels significantly differed in terms of the father's birthplace, the communicative language with friends, self-perceived proficiency, and the movie-watching language. Despite evident differences regarding the book-reading language and birthplace of the mother, these were not statistically significant. Also, no relationship was observed between HLA and some variables: Age, grade level, and AoA. This initial study attempted to comprehend the complex patterns behind the language anxiety concept in the context of Turkish immigrants in Germany and heritage language education (HLE). In conclusion, interaction via heritage language (HL) and access to HLE may contribute to reducing HLA. However, paradoxically, while HLE may alleviate general HLA, it may cause more in-class anxiety due to sociocultural and pedagogical factors.
Dyslexia in Arabic-French Bilingual Children: A Multiple-Case Study
Authors: Dalle Laurine 
Published: June 2023

Summary
Dyslexia and L2 appropriation have been extensively documented separately; however, few studies have brought them together. Our research sheds linguistic light on dyslexia in Arabic-speaking bilingual children. The aim is to study phonology, reading and spelling in dyslexic and non-dyslexic children learning French as a second language to better distinguish between what a reading disorder is and what typical appropriation is, with possible transient difficulties related to L2 development. The general hypothesis is that there are specific markers of dyslexia in Arabic-speaking children learning French as a second language. A multiple-case study was conducted. It consisted of four dyads of children aged 8-10 years: two bilingual dyslexic children, two bilingual non-dyslexic children, two monolingual dyslexic children and two monolingual non-dyslexic children. The bilingual children were Arabic speakers who had arrived in France at the age of six. In a diachronic and synchronic approach, spontaneous and experimental data were collected over a period of nine months. The experiment was based on the Phonoludos, Odedys 2, ELFE and ELDP2 tools. Parental questionnaires were also administered to parents. A synthesis of the most important results is presented. A phonological deficit is manifested in all dyslexic subjects by difficulties in speech perception/production, weaknesses in phonemic unit manipulation and decoding. In reading and spelling, atypical phonemic and phonetic errors are found in large numbers, whereas they are absent in non-dyslexics. This study is a first step in understanding how to identify dyslexia in bilingual children. It is now important to extend the study to a larger number of subjects, with a view to adapting tools that will facilitate the identification and assessment of children who speak several languages.

Aim. To Consider the issue of managing the rehabilitation process of persons with myocardial infarction in the acute period.
Materials and methods. The scientific and methodical literature on the use of physical therapy in myocardial infarction at the hospital stage was analyzed.
Results. Prescribing therapeutic exercises depends on the severity of the course of the disease. Patients are divided into 4 classes. This division is based on different types of combinations of the main indicators of the course of the disease, such as the size and depth of the heart muscle damage, the presence and nature of complications, the severity of coronary insufficiency. Physical therapy for patients with myocardial infarction consists of three periods, each of which has its own goals.
Conclusions. The direct effect of therapeutic exercises on patients with diseases of the cardiovascular system is manifested as follows: the functional state of the cerebral cortex is normalized, the well-being of patients before physical exertion improves; a positive reaction of the links of the central and peripheral apparatus of the blood circulation develops; the redox phase of metabolism improves; the function of the neurohumoral regulation of the circulatory system improves.
