Dramatization on Television News: Approach of Experts and Challenges in the Context of Disinformation
type: item
description: In the age of immeasurable amounts of information, with the rapid spread of modern information solutions and ongoing search for new forms of information transfer, the design of content is changed and entangled in various kinds of emotions. One of the most commonly used techniques is dramatization, which aims to provoke a strong emotional response from the viewer. However, in the contemporary media landscape characterized by disinformation and manipulation, this phenomenon is emerging as a cause for concern.

Discrete Limit Theorem for the Epstein Zeta-Function
type: item
description: In this paper, the value distribution of the Epstein zeta-function ζ(s; Q) is investigated. It is well known that the asymptotic behaviour of zeta-functions is most effectively defined by probabilistic limit theorems in the sense of weak convergence. A limit theorem of continuous type for the function ζ(s; Q) on the complex plane has been obtained by Laurinčikas and Macaitienė [11]. This paper presents a discrete-type result, based on the Master’s Thesis [8] by Gutauskienė.

Diversity and Inclusion Marketing for Brand Building
type: item
description: Due to evolving market trends, changing consumer needs, globalisation, social responsibility, and the demand for sustainable development, diversity and inclusion marketing has become increasingly important for brands. Despite its growing relevance in academic literature, no clear, step-by-step guidelines exist to help brands implement it effectively. This study aims to fill that gap by theoretically demonstrating the benefits of diversity and inclusion marketing and creating practical guidelines for its application. The study explores how such marketing strategies can strengthen a brand. In the first section, we define diversity and inclusion marketing and the conditions under which it can be effectively applied. The second section highlights its importance for brand development, while the third presents a roadmap for implementation. These guidelines can assist companies, managers, and marketers in initiating and applying diversity and inclusion marketing. They emphasise how it can help retain customers, understand their needs, and build meaningful connections. Additionally, it supports the creation of relevant content and fosters positive engagement among employees and management, encouraging innovation. Overall, the study offers a structured approach to using diversity and inclusion marketing as a strategic tool for brand growth and resilience.

This article aims to identify the common causes of misbehaviours in the foreign language classrooms and teachers’ response and techniques to deal with these challenges by maintaining positive discipline. The present study was conducted in the context of a workshop that involved eight foreign language teachers at a private school. The workshop was discussion based, and participants shared their challenges and techniques to deal with them accordingly. The research methodology applied was qualitative, with content analysis and the usage of inductive coding to analyse the data gathered from the workshop. The findings of the study indicate that the most prevalent causes of problematic behaviour in foreign language classrooms are academic challenges, attention seeking, and individual needs. The strategies employed to address these challenges include active engagement, personal talks, positive reinforcement, and classroom rules reminders.

Paradoxes of the Killer’s Identity
type: item
description: The article examines a short story “My Friend Sigitas” [Mano draugas Sigitas] by Alvydas Šlepikas through the lens of Jacques Lacan’s structural psychoanalysis. The main focus is placed on identification, which, unlike in the classical tradition of psychoanalytic literary criticism, is examined not as a mental act of the author or reader, but as an action of verbal communication, embedded in the literary text itself. Thus, a seemingly simple and funny story about the death of a friend is revealed to be rendered around a paradox: through various discursive operations, the homodiegetic narrator simultaneously tries to accept and reject the accusation of murder. In this way, contrary to a common assumption, a traumatic structure of discourse is associated not with a victim or witness, but the accused, i.e., the position of a potential murderer. The latter is analysed neither from the legal perspective, which due to the narrator’s justification to the addressee would be natural in empirical reality, nor by speculating about the inner experiences of the subject, as if he were a real person. By comparing this research strategy with possible alternatives, we demonstrate the differences between psychological and psychoanalytical interpretation of literature.

Expression of Leadership Abilities of Students of the Basic Music Education Programme in a Music School: A Case Study
type: item
description: The development of leadership skills is a continuous and ongoing process, starting in childhood. Leadership is associated with personal qualities – creativity, initiative, critical thinking, etc. This is not a natural trait, but something that has to be learnt, and education has an important role to play in the development of young leaders. Music school education focuses on subject achievements that are important for musical activity, on the development of artistic skills, and often overlooks the development of leadership skills that are important for personal maturity. Since it is assumed that the application of the transformational leadership model could enable the development of the expression of leadership skills, the article analyses the prerequisites for the expression of leadership skills in music school educational activities and the possibilities of their improvement in a particular music school in order to achieve the comprehensive success of a person’s (self-)education. The findings of the empirical research suggest that teachers in a music school focus on the development of musical abilities, while the development of leadership skills becomes a self-occurring consequence of the organisation of the process, rather than a well-thought-out and purposefully pursued goal.

The Effect of Duolingo on l2 Learners’ Pronunciation: Vowel Analysis through Minimal Pairs
type: item
description: The present paper focuses on the acoustic analysis of Russian speakers’ English vowel production before and after using the Duolingo application. The study aims to investigate phonetic acquisition of English vowels, particularly in the context of minimal pairs. The method chosen to achieve this objective is experimental analysis using phonetic acoustic variables – formant frequencies (F1 and F2) and vowel duration which were evaluated through spectrograms. Ten Russian-speaking volunteers participated in the experiment and were treated pre-test and post-tests. The results observed in this experiment show that Duolingo application contributed to Russian speakers’ production of tense/lax English vowel pairs /u/-/ʊ/ and /i/-/ɪ/ with F1 and F2 frequency values closer to those of British English, but no improvements were seen with the open front vowel /æ/. The duration of vowels did not see significant improvements apart from the vowel pair /u/-/ʊ/.

Empirical Analysis of Factors Preventing Pupils from Choosing stem Fields
type: item
description: As technological developments expand globally, the need for science, technology, engineering, and math (STEAM)-relate d professions has grown. Emphasis on STEAM-oriented careers and study choices has expanded in many educational systems in the world. The research focuses on students‘ attitudes towards STEM subjects inside and outside of school, their motivation to study and pursue a STEM career. Key results indicate that students have reservations in pursuing a STEAM career and that their academic and practical motivation to study STEAM varies. The study suggests that employing a diverse, practical approach towards teaching STEAM subjects could encourage more students to choose STEAM subjects and careers. Research object is to explore the factors associated with the low number of students choosing to study and pursue careers in STEM (Science, Technology, Engineering, Mathematics) fields after secondary education in Lithuania. Aim of research is to understand the factors influencing the choices of young people in Lithuania regarding STEM subjects and careers. Objectives: 1. To identify and analyse the factors that prevent students from choosing STEM fields; 2. To explore the differences in attitudes and motivations towards STEM between male and female students. Method of research: Conducting a quantitative analysis through online surveys involving 196 high school students from Šiauliai, Lithuania.

Peculiarities of Informal Music Education in an Inclusive Classroom: Analysis of Teachers’ Experiences
type: item
description: Although more and more attention is paid to the development of inclusive education in Lithuanian education, but taking into account the fact that the success of any education depends on the ability of the pedagogue to work qualitatively in various conditions, inclusive education is still full of challenges. The article reviews the approach of researchers to non-formal music education when there are SEN children in the classroom, and also, through the empirical study, the challenges faced by pedagogues when teaching music students with special needs are revealed. The research revealed that the educational context of inclusion of non-formal music education is necessary, but full of challenges: lack of suitable conditions for working with children with SEN (addapted learning environment, variety of musical instruments, need for a teacher’s assistant), limited preparation of music educators for work in an inclusive classroom, insufficient knowledge of existing music and art school teachers about the development and learning characteristics of children with SEN.

Adolescents’ Experiences in Heterogeneous Theatre Activity Groups: Aspects of Social Inclusion
type: item
description: Relationships between adolescents with disabilities and their non-disabled peers are characterised by certain tensions due to low communication experiences, so joint activities in heterogeneous groups can have a unique positive impact on each participant, while at the same time building community and social interactions. As creative and artistic activities encourage the exploration of personal strengths and abilities, engaging in them allows young people to feel like creators rather than people limited by disability. In this way, they discover new, meaningful social roles. It is important to find out what is the impact of activities in a heterogeneous theatre environment on adolescents’ social inclusion? The novelty of this study is in its retrospective approach: the participants, who are now adults, evaluated their experiences from 10–15 years ago and their relevance to their current social life, self-concept and profession. The aim of the study is to reveal the experiences of members of heterogeneous theatre groups in terms of social inclusion. The objectives of the research are: to find out the experiences of participants with disabilities, to reveal the experiences of adolescence of participants without disabilities, to analyse the experiences of participants in terms of social inclusion. The research methodology was a qualitative social research approach. Data was collected through semi-structured interviews. The method of inductive thematic analysis was chosen for data analysis. An analysis of scientific sources was carried out. Summarizing the analysis of the research, it should be noted that the participation in the heterogeneous theatre groups created positive social experiences for all participants, shaped their values, influenced their choice of profession, hobbies and had a positive impact on their quality of life. For adolescents with disabilities, activities in these groups opened up wider social experiences and creative perspectives, influenced greate…

type: item
description: By applying the method of content analysis, the article analyzes basic (grades 5–8) music textbooks by different authors. The article aims to find out how much and in what way Christian values are presented in the content of musical education. The results of the research revealed that the Christian faith, its meaning and values are most reflected in Balčytis’s series of textbooks “Muzika” (2007). Malikėnienė’s textbooks “Muzika” (2010) and “Muzikos labirintai” (2012) pay more attention to the development of students’ secularity and understanding of music.

Effects of Functional Electrical Stimulation and Transcutaneous Electrical Nerve Stimulation on Spasticity and Muscle Properties in Spinal Cord Injured Individuals
type: item
description: The goal is to investigate and evaluate the effects of FES and TENS, individuals who have suffered spinal cord injury, spasticity of paresis or plethora leg muscles, and muscle characteristics. The study was conducted in the homes of the persons. Before and after stimulation, spasticity and muscle properties were measured using the myotonometer “Myoton”. Using Compex Cefar and Compex Mini stimulants, 30 min. FES was applied to the left leg and 30 min. of the TENS program to the right leg. The study involved 10 individuals who suffered spinal cord injury. Tens showed a statistically significant increase in the elasticity of the quadriceps thigh muscle (p < 0.05), which means that the ability of the muscles to resist muscle contraction and the effects of external factors increased. All other measurements did not have a statistically reliable difference (p > 0.05). No statistically significant difference was also found between the FES and TENS groups (p > 0.05). Although FES and TENS did not have a statistically significant impact on elasticity and muscle tone, tens had a statistically significant deterioration in the muscle property of elasticity, which means that spasticity increased.

Analysis of the Occurrence of the Ash Maples in the Town of Tirkšliai
type: item
description: The study analyses the occurrence of Ash Maples (Acer negundo L.) in the town of Tirkšliai, which is located in the municipality of Mažeikiai district. The assessment survey was carried out in September–October 2023. The inventory of the Ash Maples was carried out using a route method, recording the coordinates and the conditions of the sites: area, projection coverage of individuals, level of urbanisation of the ecotope, biotope, assessment of whether or not the area of the site was mown, intensity of use of the area where the site is located. The ontogeny stage shall be assessed on the basis of the vegetative and generative characters of the ash-leaved maples and the height of the trees. The height of the individuals of the Ash Maple was determined visually, in metres, by assessing the entire length of the above-ground part of the tree. In total, 14 sites with ash-leaved maples were identified as well as 10 sites with trees of juvenile age. Most of the sites were found in grassland (64 %), 79 % in roadsides, by intensity of land use the highest number of sites were found in unused land (43 %), 50 % of the sites are not mown. It is therefore evident that the occurrence of big-leaved maple trees is higher in less maintained areas.

The application of self-directed learning redistributes the power and responsibilities of the participants of the educational process, therefore opportune preconditions are created for the change of the interaction between the pupil and the educator and for the transition from teaching to learning. Therefore, the provision is observed that the implementation of self-directed learning in educational practice changes the quality of the educational process. The article analyzes how the self-directed learning, established in the educational process of a specific music education institution (music school) that complements formal education changes the interaction between the pupil and the educator, what circumstances are significant, what are the links with the quality of the educational process. The analysis of the results of the empirical research allows us to state that teachers understand self-directed learning and its importance theoretically, but teaching itself has not become a natural strategy for organizing the educational process; fragmentary features of pupils’ self-direction are seen, positions of learning power are more characteristic of teachers than pupils.

Distribution and Control of Sosnowsky’s Hogweed (Heracleum sosnowskyi Manden.) in Klaipėda District
type: item
description: Kiekvienais metais yra užregistruojama naujų nepageidaujamų augalų augimviečių. Lietuvoje labiausiai žinomas invazinis augalas – Sosnovskio barštis (Heracleum sosnowskyi Manden.) – yra paplitęs ir Klaipėdos rajone. Jo gausūs sąžalynai pakeičia augalų bendrijų rūšių struktūrą, ypač pievų buveinėse. Be to, šis augalas kelia grėsmę žmonių sveikatai bei kenkia ūkiniams gyvūnams. Lietuvoje Sosnovskio barštis masiškai naikinamas, visgi pasirinktas tinkamas kontrolės būdas galėtų užtikrinti ilgalaikį rezultatą, kuris neleistų šiam augalui plisti. Straipsnyje pristatomo tyrimo tikslas – palyginti Sosnovskio barščio naikinimo Klaipėdos r. savivaldybės teritorijose rezultatus: vienose jų trejus metus Sosnovskio barštis buvo intensyviai naikintas, o kitose – tik vykdyta minimali šio invazinio augalo kontrolė. Tyrimo rezultatai parodė, kad Sosnovskio barščio naikinimas mechaniniais ir cheminiais metodais yra efektyvesnis nei tik invazinio augalo šienavimas. Pateiktos rekomendacijos leis atidžiau rinktis kontrolės priemones Sosnovskio barščio plitimo rizikai sumažinti.

Study of the Distribution of River Beaver (Castor fiber) in the Liuoba and Guntinas Rivers
type: item
description: River beaver’s (Castor fiber) lifestyle and ability to survive influence nature ecosystems. Beavers in their living environment raise the water level and thus flood areas of forest and land. This paper analyzes the results obtained from the assessment of river beaver habitats in two rivers with different water discharges. The study to determine the activity of beavers and their impact on the environment was carried out in October-November 2023. Active beaver sites were determined by fresh crawl paths and fresh tree bites. There are two types of beaver biotopes in the territory of north-western Lithuania chosen for the study: large and small natural rivers. The monitoring of beaver sites was carried out by investigating the studied area along Luoba – a large natural river and Guntinas – a small natural river. The number of beavers hunted in Skuodas district is 3.4% of Lithuania. During the examination, fourteen beaver sites were discovered, which were located in beds of Luoba and Guntinas rivers. There were 60% more beavers in the Guntinas than in Luoba. The average distance between active beaver sites is 279 meters. During the study, after counting the gnawed woody plants near the beaver habitats, the main plants used in beaver’s diet were identified: willow (30%), aspen (21%), and birch (18%).

type: item
description: This article actualises the importance of education of moral values nurturing a full-fledged personality. Acknowledging the meaning and particularity of education of moral values in ontogenesis, the particular importance of primary education of moral values in the childhood is pointed out. Play stands out as one of the factors that determines the education of moral values processes in current world. On the basis of the scientific sources and data of researches, play is defined as the main child’s activity. Having discussed the effective use of child’s play in education of moral values (in this article from the holistic point of view), the varied influence of play on child’s education of moral values is revealed. Evaluating this effect from the point of view of child’s moral self-development, it is stated that through naturally occurring situations during play, a child is exposed to real possibilities to express moral values that help her//him to better adjust to their peers, to involve into group’s life and to achieve a favourable status. In terms of child’s individuality development, a child is able to acquire new moral abilities, skills, individual experience, norms and regulations, to experience joy and pleasures. Generalising, play may lay valuable foundation for the development of child’s moral and individual personality, which allows for considering play as a significant factor of education of moral values in the childhood.

Impact of Alcohol Consumption Restrictions on Negative Traffic Accidents on Lithuanian Highways
type: item
description: The article uses statistical data from the Lithuanian Road Police Service on traffic accidents, speeding, drinking and driving (DUI), and people injured in traffic accidents on Lithuanian highways, i.e., negative traffic accidents in the period of 2000–2018. The aim of the work is to analyse the dynamics of traffic collisions and circumstances related to them. To achieve this aim, the negative accident data recorded on Lithuanian highways was converted into a 1-mile (8 km) unified system by grouping roads according to their length: small, average, large, and the largest roads. Time series AR(1) models were found for most of the cases. By employing statistical methods, it was identified that the 2008 law restricting the sale and advertising of alcohol led to the following results: a reduction in traffic accidents and the number of intoxicated drivers on all roads, although at the same time there was an increase in speeding. The number of people injured on small roads has increased.

The Investigation of the Discrete Universality of L-Functions of Elliptic Curves
type: item
description: In the paper, we prove the discrete universality theorem in the sense of the weak convergence of probability measures in the space of analytic functions for the L-functions of elliptic curves. We consider an approximation of analytic functions by translations LE (s+imh) , where h > 0 is a fixed number, the translations of the imaginary part of the complex variable take values from some discrete set such as arithmetical progression. We suppose that the number h > 0 is chosen so that exp{2πk/h } is an rational number for some non-zero integer. The proof of discrete universality of the derivatives of L-functions of elliptic curves is based on a limit theorem in the sense of weak convergence of probability measures in the space of analytic functions.

The Influence of Manager’s Trustworthiness on Subordinate’s Trust in the Manager
type: item
description: Trust in the organization makes the leadership for the manager easier, contributes to the achievement of the goals. Real and sustainable trust determines the reliability of the entire organization and supports the corporate reputation. A person’s trust in another person eventually leads to the trust of the entire system. Behaviour is a significant determinant of organizational trust. The strongest relationship is between the trustworthiness of the manager and the trust of the subordinate. However, previous studies lack the dimensions of trust. Therefore, in this study, research on the influence of the trustworthiness of the manager on the trust of the subordinate in the manager includes dimensions of each key concept. The purpose of the study is to determine the influence of the trustworthiness of the manager on the subordinate’s trust in the manager. A theoretical model as a background of the research is presented. It is composed of five dimensions of the trustworthiness of the manager, that is, consistency of manager behaviour, integrity of behaviour, sharing of control, and communication and demonstration of concern, and their influence on the general trust, as well as cognitive and emotional trust of subordinates in the manager. The results of the regression analysis have revealed that the greatest positive influence on the subordinate’s trust in the manager is the manager’s demonstration of concern, but this influence is greater on emotional trust than on cognitive trust. The integrity of the leader’s behaviour also has a positive effect on general and both cognitive and emotional trust of the subordinate in the leader. Additionally, consistency of behaviour, communication, and sharing of control contribute to the accuracy of predicting trust, but the influence of each of these dimensions of the trustworthiness separately is not significant. The results of the study have also shown that the trust of the subordinate increases with the increase in the ratio of th…
