This paper deals with the specialized corpora building, specifically academic language corpus in the biotechnology field. Being a part of larger research devoted to creation and usage of specialized parallel corpus, this piece aims to analyze the initial step of corpus building. Our main research question was what procedures we need to implement to the texts before using them to develop the corpus. Analysis of previous research showed the significant quantity of papers devoted to corpora creation, including academic specialized corpora. Different sides of the process were analyzed in these researches, including the types of texts used, the principles of crawling, the recommended length of texts etc. As to the text processing for the needs of corpora creation, only the linguistic annotation issues were examined earlier. At the same time, the preliminary cleaning of texts before their usage in corpora may have significant influence on the corpus quality and its utility for the linguistic research. In this paper, we considered three small corpora derived from the same set of academic texts in the biotechnology field: “raw” corpus without any preliminary cleaning and two corpora with different level of cleaning. Using different Sketch Engine tools, we analyzed these corpora from the position of their future users, predominantly as sources for academic wordlists and specialized multi-word units. The conducted research showed very little difference between two cleaned corpora, meaning that only basic cleaning procedures such as removal of reference lists are can be useful in corpora design. At the same time, we found a significant difference between raw and cleaned corpora and argue that this difference can affect the quality of wordlists and multi-word terms extraction, therefore these cleaning procedures are meaningful. The main limitation of the study is that all texts were taken from the unique source, so the conclusions could be affected by this specific journal’s peculiarities. Therefore, the future work should be the verification of results on different text collections

Aims and research questions: This paper presents a new study addressing the issue of cross-linguistic influence in acquisition of referring expressions. The main research question is how to predict directionality of this influence in a dual language development. Methodology: The method is an elicited production task. We consider the phenomenon of direct object referring choices, i.e. noun, pronoun and null element, in a ‘null-object’–‘overt-object’ language pair (Ukrainian and English). Data and Analysis: Participants of the experiment are 4–6-year-old Ukrainian–English bilinguals (N20) and Ukrainian monolinguals (N21). The data are analyzed in the statistical program R, utilizing the R-library function lme4. The results are presented as odds ratios (ORs) of each direct object type. Findings: Our data reveal that while there is no significant difference in Ukrainian object types in most of the age groups, there is a considerable amount of null object usage in English at the ages of four to five. Originality: The innovative nature of this study lies in: (i) the consideration of a licit object omission at a later stage of language development (from 4 to 6 years of age); (ii) the examination of an under-investigated language combination (i.e. English and Ukrainian); and (iii) the innovative approach to linguistic data analysis (e.g. comparing OR values). Implications: Our findings suggest that the directionality of influence in dual language acquisition depends on the developmental stage, language-specific means of syntax–pragmatics interaction, and extra-linguistic input-related factors. At the early stages of development, the null-object language is likely to influence the overt-object language, especially under conditions of limited exposure to the latter.

Technology is changing the world we live in. It affects the way people see, think, and learn their environment and communicate with others. In the educational field, there have been previous studies revealing the positive attitudes toward the use of mobile devices and applications. However, the empirical studies of the practice of how to use a specific mobile device and application effectively are done in a limited scale. Taking the experimental research method, this study investigated the effectiveness of the use of Instagram application on the students� performance in writing descriptive texts. The main research question was centred around whether there was significant difference in the ability of writing descriptive text between students who were taught using Instagram and those who aren�t. Involving random sampling technique, this study involved 50 students of a private high school in Yogyakarta as the research sample.� The empirical data were collected through pre and post tests. The data were analyzed quantitatively applying t-test computation and descriptive analysis. Results of the study indicate that there is significant difference in students writing score between those taught using Instagram and those who aren�t. In conclusion, teaching students writing by using Instagram pictures are more effective than teaching without using Instagram pictures. In other words, the use of Instagram is effective in teaching writing descriptive texts. �Keywords: technology; Instagram; experimental research; writing descriptive text.

Having a clear vocabulary profile of Moroccan master students might reveal where these participants stand compared to other countries. Therefore, the study aims to investigate the effect of languages of instruction in Morocco (e.g., Arabic vs. French) on the receptive vocabulary size of EFL Moroccan master students (e.g., departments of letters, science, and law). To this end, Meara’s (2010) Yes/No test was used as an instrument to measure the overall vocabulary size of these participants. A total of 325 EFL master students took the aforementioned test. The main research question is: Does the medium of instruction have any effects on the receptive vocabulary size of these students? Descriptive statistics were employed to calculate the overall receptive vocabulary size of test-takers. It was found that Moroccan EFL master students have a total of (M= 2293) lemmas. An independent samples t-test was run to check for any statistical significance. The t-test statistic reveals that the significance level is less than the p-value (t=-4.068, p< .05, df= 323). Thus, it was concluded that there was a statistically significant difference between the French group and the Arabic group. The results of this study confirm that students who were instructed in French (M= 2417, sd= 903, N=185) outperformed the other students who were taught in Arabic (M= 2058, sd= 903, N= 140). In the current study, among various suggestions, it is proposed that the volume of 30 hours in the English module is not sufficient and should be complemented with vocabulary-based activities.

Climate resilience competencies improve people’s capacity to recognize and adopt strategies for mitigating negative climate effects. Especially concerning the built cultural heritage protection in the coastal areas, both professionals and citizens have to be prepared for water-related extreme events, such as floods, sea-level rise, and altered precipitation. Considering these challenges, the authors explore the efficiency of serious video games and describe the process of design and validation of the pilot educational online maze game “Let us save Venice”. More specifically, the main research question motivating the study is to identify what the experience factors and the mini-games are that contribute mostly to raising awareness to climate resilience and built heritage sustainability. The question implies two main research objectives: first, to explore what role user-centered game design plays in creating immersive and enjoyable educational video maze games, and second, to investigate which factors influence user experience and game playability in the design phase, and how they contribute to learnability and raising awareness. The background section of the article focuses on a preliminary study of the educational potential of serious games and introduces the EU-funded project e-Creha. Then, it explores the process of game design, development, and validation, focusing on metrics such as game learnability and game experience. The results outline the main findings that immersion, positive affect, and competence appeared to be the main experience factors contributing to raising awareness to climate resilience and built heritage sustainability. Lastly, the discussion section provides further directions for game improvement and future work.

The subject of this paper encompasses US policy towards Poland and the Baltic States regarding energy security during Donald Trump’s presidency. It is discernible that vast domestic energy resources have created an opportunity for the US to project more power to these countries, and the surrounding region. We argue that Trump and his administration’s perceptions have served as an intervening variable in that opportunity assessment, in accordance with the neoclassical realist theory. The main research question addressed in this paper is whether US has used that opportunity to contribute to energy security in countries it has traditionally deemed as allies. Two aspects of US approach to energy security of the designated countries are taken into consideration: liquified natural gas exports and support for the Three Seas Initiative. The way Trump presented his policy and its results in his public statements has also been considered in this paper. The article will proceed as follows. The first subsection of the paper represents a summary of energy security challenges in Poland and the Baltic States. The second subsection is dedicated to the opportunity for the US to project energy power and to Trump’s perceptions relevant for the opportunity assessment. The third subsection deals with American LNG exports to these countries as a possible way for contributing to energy security in Poland and the Baltic States. The last part of the paper addresses the Three Seas Initiative and US approach to this platform.

AbstractA large number of studies have demonstrated the benefits of natural environments on people’s health and well-being. For people who have limited access to nature (e.g., elderly in nursing homes, hospital patients, or jail inmates), virtual representations may provide an alternative to benefit from the illusion of a natural environment. For this purpose and in most previous studies, conventional photos of nature have been used. Immersive virtual reality (VR) environments, however, can induce a higher sense of presence compared to conventional photos. Whether this higher sense of presence leads to increased positive impacts of virtual nature exposure is the main research question of this study. Therefore, we compared exposure to a forest and an urban virtual environment in terms of their respective impact on mood, stress, physiological reactions, and cognition. The environments were presented via a head-mounted display as (1) conventional photo slideshows or (2) 360$$^{\circ }$$ ∘ videos. The results show that the forest environment had a positive effect on cognition and the urban environment disturbed mood regardless of the mode of presentation. In addition, photos of either urban or forest environment were both more effective in reducing physiological arousal compared to immersive 360$$^{\circ }$$ ∘ videos.

Surface modification is used to extend the life of implants. To increase the corrosion resistance and improve the biocompatibility of metal implant materials, oxidation of the Ti-13Nb-13Zr titanium alloy was used. The samples used for the research had the shape of a helix with a metric thread, with their geometry imitating a dental implant. The oxide layer was produced by a standard electrochemical method in an environment of 1M H3PO4 + 0.3% HF for 20 min, at a constant voltage of 30 V. The oxidized samples were analyzed with a scanning electron microscope. Nanotubular oxide layers with internal diameters of 30–80 nm were found. An analysis of the surface topography was performed using an optical microscope, and the Sa parameter was determined for the top of the helix and for the bottom, where a significant difference in value was observed. The presence of the modification layer, visible at the bottom of the helix, was confirmed by analyzing the sample cross-sections using computed tomography. Corrosion tests performed in the artificial saliva solution demonstrated higher corrosion current and less noble corrosion potential due to incomplete surface coverage and pitting. Necessary improved oxidation parameters will be applied in future work.

The aim of the research presented in the paper is to explore the inter-relations between care processes and personal social networks as social capital in the light of the changing family models. Research of interdependence of care, social capital and family models is based on the idea of family practices suggested by Morgan. The main research question is what family practices of various family models create such social capital that ensure caring for its' members? The research hypothesis is that participation in various activities together with family members and persons beyond nuclear and extended family create dense social networks of caregivers. The analysis is based on data of representative quantitative survey carried out in Lithuania between 2011 November-2012 May within the ESF supported research project "Trajectories of family models and social networks: intergenerational perspective". Research results only partly support this hypothesis: particular family practices create networks of caregivers, but in order to involve particular persons into network of caregivers, different family practices in various family models are needed. Usually, inhabitants of Lithuania primarily expect to receive care from persons who depend to nuclear family created through marriage and extended family arisen from this relation. But persons from whom it is expected to receive care and care received differ in Lithuania. In reality, caregivers usually are children in families with children and parents in families without children. Family practices that create social networks of caregivers, and are common for all family models include annual feasts like Christmas Eve, Christmas, Easter, All Soul's Day, New Year party, Mother's Day. Various family practices differently impacting creation social networks of caregivers for different family models but usually its include joint dinner daily, Sunday lunch together, vacations with family, communication face-toface, by the telephone or Internet, consultations on important decision-making, All Soul's Day feast, Christmas celebration, Mother's Day, Gatherings of relatives, Birthday, Name-day feast, visiting cultural event together.

The purpose of this study is to determine the demographic profiles of the respondents which are the teachers in Mindanao State University–Sulu according to gender and college, to identify the issues encountered by the MSU-Sulu Teacher towards modular distance learning approach, to distinguish the concerns of the MSU-Sulu Teacher towards modular distance learning approach, to investigate the teaching preparations on the adaptation of modular distance learning approach, and to identify the significant difference of issues and concern of the MSU-Sulu Teacher towards modular distance learning approach when they are grouped according gender and college. Frequency and percentage distribution, weighted arithmetic mean and independent t-test and chi-square are the statistical tools used to answer the entire research question. The data gathered was computed using SPSS analyzed and interpreted with the aide of the statistician. Descriptive survey method was used as the research method. This study utilizes 40 teachers from different colleges/department. Convenience sampling was used to It is the recommended number of which it is the 30% from the total population of all the faculty of Mindanao State University-Sulu.; questionnaire is used by the researcher as a research instrument of the study. The findings of the study were: 1) There is no significant difference of issues and concern of the MSU-Sulu teacher towards modular distance learning approach when grouped according gender but in contrary; and 2) There is significant difference on the issues and concern among MSU-Sulu teacher towards modular distance learning approach when grouped according colleges. The issues encountered towards modular distance learning approach were communication failure like that of instructions or confusion of students on the modules, limited teacher guidance, student’s in discourteous approach to teachers, complaints on not understanding the module, and all of which results to misbehavior on students and failure to pass worksheet on time. In addition, the concerns of the MSU-Sulu teacher towards modular distance learning approach were; first, hidden expenses on modules; second, teacher’s lack of media literacy; third, poor internet connection which intercepts communication between teacher and students; fourth, time constraint among teachers due to overload paperwork; fifth, equipment problem and complexity of the discussion as well as measurement of student’s performance; sixth,  managing student’s responses from time to time; seventh, teacher’s unavailability  and lastly, difficulties of studying among slow learners. Moreover, on teaching preparations on the adaptation of modular distance learning approach, the issues were cater and set time for student’s inquiries and be flexible to allow extension in terms of passing worksheets as well as allow parents, relative or even friends to pass worksheets in their behalf to lessen transportation expenses. Teachers must appreciate/ recognize his/her students to boost their confidence and avoid favouritism while being considerate to students who are attention seeker or may have ADHD. Correspondingly, the concerns were. Teachers must encourage handwritten answers to lessen plagiarism, on the absence of teacher, the parents and elders must guide the students in their learning at home. Teacher and parent’s guidance must go hand and hand in today’s learning. Teachers must likewise be flexible in finding solutions on printing shortage. And lastly, alternative teaching strategies like modular learning should be hone to aid lack of media literacy of both teacher and students In view of the findings and analysis, the following are recommended: Teachers must be flexible with the present kind of teaching strategy at all cost and at all aspects, Set guidelines as to establish proper communication among students and teachers, learning materials must be affordable as well as easy to understand content, teachers must develop their media literacy skills and encourage teachers to be available to their students on allotted time and cater all their inquiries with patience at all times. Furthermore, the following are the recommended research agenda: Teacher’s training on media literacy and module development programs to allow teamwork in the making process.
