From Emergency Remote Teaching (ERT) to Sustained Remote Teaching (SRT): A comparative semester analysis of exchange students’ experiences and perceptions of learning online during COVID-19
Authors: Stewart William H. , Baek Youngkyun , Lowenthal Patrick R.
Published: June 2022

The COVID-19 pandemic caused universities worldwide to close campuses, forcing millions of teachers and students to resort to Emergency Remote Teaching (ERT) and learning. Though necessary, the sudden move to remote delivery marked a significant departure from the standards and norms in distance education. In Korea, the pandemic coincided with the start of the 2020 academic year. Though ERT was new and unplanned during the first semester of the year, it became Sustained Remote Teaching (SRT) in the second. Through the lens of performance improvement theory, we sought to determine if students’ experiences and perceptions with learning remotely via SRT would change over time as a result of institutional preparedness and faculty support/experience. In total, 140 (Spring) and 93 (Fall) exchange students rated their perceptions of Teaching and Learning Processes, Student Support, and Course Structure with their ERT/SRT learning experiences via an electronic survey. An independent-samples one-way ANOVA indicated several statistically significant benchmarks, though results are interpreted as minor real world improvement. Implications for ERT/SRT policy and future research in the context of specific student groups are discussed.
Predicting social presence in videoconference-supported LMS courses: Mediation through L2 writing and speaking strategies
Authors: Bailey Daniel , Almusharraf Norah , Almusharraf Asma
Published: June 2022

The issue addressed here concerns how second language (L2) speaking strategies mediate the relationship between L2 writing strategies and the social presence component of the community of inquiry (CoI) framework within the context of fully online courses that combined learning management system (LMS) for writing tasks and videoconferencing for live classroom discussion. L2 writing strategies related to planning and reviewing contribute to composing tests that students want to upload, present, and discuss, and this sharing is expected to foster classroom social behaviors and consequent language gains. For the current study, a cross-sectional survey of 256 university students was initiated to investigate the mediating effect L2 speaking strategies have on the relationship between L2 writing strategies and social presence. The results indicated positive path coefficients between review strategies and speaking strategies, review strategies and social presence, planning strategies and speaking strategies, and speaking strategies and social presence. Further, speaking strategies explain the relationship between planning strategies and social presence, indicating full mediation. Partial mediation was found for the path between review strategies and social presence. Recognizing how L2 writing and speaking strategies relate to one another and how that relationship influences a CoI illustrates the interconnectivity between language skills. Evidently, increased attention to planning and reviewing strategies results in a final composition worth sharing and discussing, and such sharing and discussion are building blocks to a vibrant social presence.

Authors: Parte Laura , Mellado Lucía
Published: June 2022

This study sheds light on the relation between assessment modalities and student behavior through linguistics styles, and academic performance. First, we examine the effect of assessment modalities (self-evaluation quizzes and summative quizzes) on academic performance. Using two modalities of online quizzes, we mainly focus on the student participation, student behavior (the work pacing and time management), type of assessment, and student characteristics. Second, we analyze the student behavior through linguistic styles and third, we examine the levels of anxiety and the expectation of success during the course. Specifically, we compare the linguistic styles of high performing students and low performing students and changes in anxiety levels and expectation of success. Methodologically, this study includes a static and dynamic perspective and combines quantitative analysis with a qualitative approach. The participants are students enrolled in Managerial Accounting for Tourism course in the academic year 2019–2020. The results show that both quizzes modalities are positively associated with academic performance. The linguistic analysis shows differences in the language between high performing students and low performing students. Finally, a pattern of changes on the students’ expectations of success and levels of anxiety are identified during the course.

Published: June 2022

Healthcare professionals deal with the greatest prevalence of burnout syndrome (BS). The object of this paper is to study the effect of psychological climate and working conditions on risks of burnout in a team of healthcare professionals. Working conditions of 136 healthcare workers from the Saratov region who underwent little training were examined according to Regulation 2.2006–05. The level of burnout was estimated in accordance with the method of V. V. Boyko, and the psychological climate in a team was analyzed using A. F. Fiedler’s questionnaire. The results were processed with the help of Microsoft Еxcel 10 for Windows. Based on the research results, the BS signs were recorded in 52.3% of healthcare workers. Physical and emotional symptoms were predominant BS signs. Factors predisposing to BS in healthcare workers have been determined. It is established that there is a dependence between a harmful factor of working conditions and probable BS. The dependence acquires significance at 3.2 level of working conditions. It is determined that the risk of BS was 74.3% in the most unfavorable psychological climate, and didn’t reach 21% if the climate was favorable.
Diseño narrativo de formato largo de la transmisión
Authors: Notariano Belizário Pedro , Massarolo João Carlos
Published: June 2022

Este artículo nace de la propuesta de relacionar los estudios de guión con los estudios de los nuevos hábitos de consumo del espectador. En esencia, explicaremos el fenómeno de la maratón de series a partir del análisis del diseño narrativo de series complejas, identificando en la macroestructuración de este formato las cualidades específicas que promueven este fenómeno en el espectador. De manera más exhaustiva, haremos nuestro análisis comparando las estructuras narrativas de series y películas, señalando las diferencias entre los diseños narrativos de estos dos formatos, que hacen imposible que una serie sea comparada con una película extendida. Básicamente, intentamos desmentir la idea de que “a medida que evolucionen los hábitos relacionados con la forma de ver las series de televisión, tenderán a ser cada vez más concebidos y escritos como un largometraje” (KALLAS, 2016, p. 16). De esta afirmación de Kallas, entrelazando conceptos de hábitos de consumo con los de guion, surgen algunas preguntas: si una serie es como un largometraje, ¿por qué nos quejamos de la duración de los largometrajes, como El irlandés de Martin Scorsese, con sus aburridas 3.5 horas de duración, mientras podemos ver maratones de series completas que contienen al menos el doble de horas? Si una serie es como una película larga, ¿por qué está dividida en episodios incluso cuando estos se pueden ver en secuencia (maratones)? Si una serie es como un largometraje, ¿por qué necesita la elaboración colaborativa de una sala de escritores en lugar de ser concebida por un solo autor? Por no decir que esta comparación estructural entre películas y series sea imposible, mostraremos cómo es problemática o, al menos, perjudicial para el análisis de las series complejas como formato autónomo, con sus propias nociones de elaboración y estructuración. En este sentido, a diferencia de las películas, las series se construyen a partir de una estructura de repetición de actos dentro de la misma, episodios que generalmente tienen de 3 a 5 actos cada uno. Esto da como resultado una mayor densidad narrativa de la serie, ya que los actos comprimidos en el tiempo conducen a un ritmo de narración más rápido, con puntos argumentales más recurrentes en la historia, capaces de intensificar el engagement y aumentar la capacidad de atención del espectador que realiza la maratón. Tal cantidad de actos, arcos narrativos y personajes van más allá de la capacidad creativa de un solo autor, requiriendo una elaboración colaborativa de una sala de guionistas, con varias cabezas pensando la historia simultáneamente. Así, este artículo busca, a partir de la comparación de las macroestructuras de series y películas, señalar las diferencias en el diseño narrativo de estos dos formatos. En otras palabras, pretendemos dilucidar un concepto simple: diferentes formatos presuponen la existencia de diferentes diseños narrativos.

Este artigo nasce da proposta de relacionar o estudo do roteiro com o estudo dos novos hábitos de consumo do espectador. Em essência, explicaremos o fenômeno do binge-wathching (compulsão), a partir da análise do desenho narrativo de séries complexas, identificando na macroestruturação deste formato suas qualidades específicas que promovem a maratona do espectador. De forma mais abrangente, faremos nossa análise comparando as estruturas narrativas de séries e filmes, apontando as diferenças entre os desenhos narrativos desses dois formatos que impossibilitam a comparação de uma série com um filme extenso. No fundo, procuramos refutar a ideia de que “à medida que evoluem os hábitos relacionados com a forma de ver séries televisivas, tendem a ser cada vez mais concebidos e escritos como um longa-metragem” (KALLAS, 2016, p. 16). A partir dessa afirmação de Kallas, entrelaçando conceitos de hábitos de consumo com os de roteiro, surgem algumas questões: se uma série é como um longa-metragem, por que reclamamos da duração de longas-metragens, como O Irlandês, de Martin Scorsese, com suas maçantes 3,5 horas de duração, enquanto consegue fazer uma maratona de séries inteiras contendo pelo menos o dobro de horas? Se uma série é como um filme longo, por que ela é dividida em episódios, mesmo quando podem ser assistidos em sequência – compulsivamente? Se uma série é como um longa-metragem, por que precisa da elaboração colaborativa de uma sala de escritores, em vez de ser concebida por um único autor? Para não dizer que essa comparação estrutural entre filmes e séries seja impossível, mostraremos como ela é problemática ou, no mínimo, prejudicial para a análise de séries complexas como formatos autônomos, com noções próprias de elaboração e estruturação. Neste sentido, ao contrário do cinema, as séries são construídas a partir de uma estrutura de repetição de atos dentro da estrutura — episódios que geralmente possuem de 3 a 5 atos cada. Isto resulta em uma maior densidade narrativa da série, uma vez que os atos comprimidos no tempo levam a um ritmo de narração mais rápido, com pontos de trama mais recorrentes na história, capazes de intensificar o engajamento e aumentar a atenção do espectador que pratica a compulsividade. Tamanha quantidade de atos, arcos narrativos e personagens vão além da capacidade criativa de um único autor, exigindo a elaboração colaborativa de uma sala de roteiristas, com várias cabeças pensando a história simultaneamente. Assim, este artigo busca, a partir da comparação das macroestruturas de séries e filmes, apontar as diferenças no desenho narrativo destes dois formatos. Em outras palavras, pretendemos elucidar um conceito simples: diferentes formatos pressupõem a existência de diferentes narrativas de design.
Bio esboços: Um processo iterativo que permite reconhecer, extrair e adaptar as características essenciais dos modelos biológicos
Authors: Angulo Camilo
Published: June 2022

Processos de ideação inspirados em modelos biológicos são uma das metodologias que os professores implementam no estúdio de design do primeiro ano, a partir de uma abordagem interdisciplinar que permite combinar métodos de design e biologia, com o propósito de que os alunos adquiram a capacidade de reconhecer e compreender estruturas da natureza que facilitam o desenho de conceitos e formas em seus esboços. Além de criar ideias, esta metodologia nos permite reajustar a relação entre o mundo artificial criado pelo ser humano e seu ambiente natural. Com o objetivo de que os alunos possam refinar os padrões estruturais da Natureza através de um processo cíclico de desenho de esboços, propomos trabalhar um modelo de iteração incremental em três etapas, onde são desenvolvidos diferentes níveis de pensamento que, ao final do processo de ideação, conduzem à solução de um projeto com altos níveis de inovação e sustentabilidade (Benyus, 1997; Arciszewski e Cornell, 2006; Nagel et al., 2018). O primeiro loop de iteração dos bio esboços tem um baixo nível de abstração, onde os desenhos são elementares e se limitam a imitar a forma direta e superficial, usando imagens de referência. Na Natureza, é encontrada como uma estratégia evolutiva conhecida como mimetismo, que, ao copiar algumas características, aumenta as chances de sobrevivência. Inclui o estudo de categorias da morfologia em termos de forma, geometria e contornos dos organismos vivos. O segundo loop de iteração dos bio esboços tem um nível de abstração médio; estuda os processos em contexto, como um estado de mudanças no ambiente físico, no qual uma série de elementos se inter-relacionam. Na Natureza, ela é encontrada como o princípio biológico de adaptação. Inclui o estudo de categorias de comportamento em termos de processos de resposta a estímulos. O terceiro loop de iteração dos bio esboços tem um alto nível de abstração, que busca novos conhecimentos a partir de uma compreensão profunda para imitar os sistemas, princípios e estratégias ou padrões, que, na Natureza, são encontrados como o princípio biológico da mutação. Inclui o estudo de categorias da fisiologia em termos de funções de sistemas vivos, subsistemas e suas partes. Por outro lado, a estratégia que usamos para alcançar uma abordagem de design inspirada biologicamente por problemas é contrária à formulação tradicional em projetos de design que começam a partir de um briefing, com um problema de design claramente definido. Tudo começa a partir de algumas soluções biológicas já existentes, das quais um princípio útil é extraído em qualquer uma de suas escalas (célula, tecido, órgão, sistema), com o qual a Natureza conseguiu cumprir uma tarefa (Wiltschnig et al. 2013) e, posteriormente, um processo de busca de um problema de projeto é realizado, ao qual este princípio pode ser aplicado com precisão.
Agua, sostenibilidad y poética en las obras del grupo cAt
Authors: Braz Soraya , Dorta Rodrigo , dos Santos Caio , Fogliano Fernando , Hildebrand Renato , Milano Bárbara , Nunes Fabio , Rubini Tiago , Sogabe Milton
Published: June 2022

Desde 2015, el grupo de investigación cAt (ciencia, arte, tecnología) del Instituto de las Artes de la UNESP (Universidad Estadual de São Paulo) reflexiona sobre las producciones Arte-tecnología, que plantean inquietudes sobre la sustentabilidad relacionada con las fuentes de energía y las posibilidades alternativas de generación de energía sin el uso directo de computadoras y aparatos de tecnología compleja, manteniendo los aspectos relevantes de las obras digitales interactivas, como el uso de la tecnología, la interacción con la audiencia y una visión sistémica. Estas inquietudes se introdujeron inicialmente en la producción de la obra “Sopro” (“Soplo”) iniciada en 2015, que es una obra interactiva impulsada por la participación del público a través de la fuerza de un viento que sopla en un molinillo. Este trabajo se basa en el uso de un sistema tecnológico sencillo, buscando la dimensión poética del acto de soplar y sus principios científicos primarios. A partir del desarrollo de este trabajo, el grupo buscó la posibilidad de crear una serie de trabajos enfocados en inquietudes acerca de la sustentabilidad con dinámicas de interacción originales, creando así nuevos sistemas y obras en las que el cuerpo de la audiencia se convierte en la fuente de poder. En este contexto, no solo son importantes las obras resultantes, sino, sobre todo, el proceso creativo, en el que los artistas centran sus inquietudes e investigaciones en temas socioambientales, asumiendo así una nueva visión del mundo, buscando nuevas actitudes y nuevas relaciones con los individuos y comunidades involucradas en este proceso, transformando sus formas de vida y materializándolas en Arte. En este artículo presentamos las obras que forman parte del tríptico, teniendo cada una de ellas un aspecto diferente, pero relacionado con las demás. Las obras se presentan en formatos esféricos, cúbicos y cilíndricos. La relación física del público con la obra se da a través de una actividad corporal, soplando, tocando y moviendo una parte de la pieza. El agua está siempre presente, pero en un estado físico diferente en cada caso, formando parte del sistema tecnológico y de la construcción poética. En este artículo nos centramos en el elemento agua, aunque en las obras están presentes otros aspectos tecnológicos y simbólicos. En la obra “Sopro”, en estado líquido, el agua representa el contexto en el que surge la vida. En la segunda obra, “Toque”, en estado sólido, el agua sirve como parte del proceso tecnológico, en alianza con el contacto humano, con el contraste de frío y calor para la generación de energía. Finalmente, en la tercera obra, “Gesto”, el agua representa la parte simbólica de la obra, relacionada con el paso del agua de estado líquido a gaseoso, como la condensación que se produce en el proceso de lluvia.

Authors: Levrints (Lőrincz) Marianna
Published: June 2022

Ukraine’s commitment to reforms in its educational sector has intensified the need for up-to-date information in terms of the prospects of its development. The problem of foreign language teacher education in the USA remains an underresearched area among the Ukrainian academia, despite the wide recognition of its considerable achievements in the world education arena. This paper set out to explore the possibilities of deploying the progressive ideas of the US experience to renew the Ukrainian system of foreign language teacher preparation. In the study, the methods of comparative analysis and scientific extrapolation were utilised. The obtained comparative data of tendencies of development and functioning of educational systems of the USA and Ukraine served as a basis for discerning future directions of modernisation of the Ukrainian system of language teacher preparation, taking into account innovative ideas of the American experience. It was contended that to expedite the quality of the Ukrainian system of language teacher preparation, the following steps could be taken: adoption and implementation of standards of professional training and development of language teachers; reformatting the content of university programmes by emphasising the block of disciplines related to language teaching, as opposed to linguistics and other general content areas; introducing in the Ukrainian universities education tracks, which open the possibility to choose between the advanced preparation in the applied issues of language teaching or its scientific aspects; updating the didactic approaches of professional competencies development; restructuring and rationalisation of approaches used during teaching practicum, to name just a few.

DISSEMINATION OF IDEAS OF PSYCHOANALYTIC PEDAGOGY IN THE RESEARCH OF THEORETISTS OF NEO-FREUDIANISM
Authors: Nelin Ievgen
Published: June 2022

The purpose of the article is to reveal the views of neo-Freudians on the problem of personality upbringing and the use of psychoanalysis in education. To achieve this goal, a set of theoretical methods was used: literature analysis, synthesis, interpretation and generalization. The article analyzes the contribution of neo‑Freudians to the spread of the theory and practice of psychoanalytic pedagogy. The key ideas of E.Fromm, K.Horney, H.S.Sullivan and A.Cardiner on the problems of personality formation, philosophy of education, organization of education and upbringing of the future generation are revealed. It is established that the views of the neo-Freudians were related to the ideas of anti-pedagogy and consisted in the deschooling and dissemination of alternative educational technologies. In particular, E.Fromm criticized the school for the fact that its main goal is to provide each student with a clearly defined amount of "cultural heritage". Horney's research was devoted to the social conditions of child development and the formation of feelings of anxiety. H.S.Sullivan studied the phenomena of individuality and self. The self is the result of experiencing educational influences, which aims to reduce feelings of anxiety and excitement. A.Cardiner's research was dominated by the thesis that the "primary institutions of every culture" have a decisive influence on the formation of personality. Inn contrast to the Freudians, who viewed the individual in the context of biological conditioning, the neo-Freudian ideas focused on the social environment, the culture in which the individual grows. The concept of psychoanalytic pedagogy in the views of neo-Freudians has acquired the features of cultural anthropology and began to take into account the ideas of social philosophy in education.

Authors: Povidaichyk Mykhailo , Yurchenko Nataliia , Shtymak Anatolii
Published: June 2022

New socio-economic and political conditions that have been forming in Ukraine in recent years, European integration processes cause an increase in the requirements for the professional training of future specialists who are competitive in the global labor market. Competitiveness is understood as a set of superiorities, manifested in the unique abilities of a modern specialist. Competitiveness is an indicator of successful professional activity, the ability to be more in demand compared to others due to many qualities that determine a high level of professionalism in their field. The purpose of the article is to substantiate the socio-pedagogical preconditions for the formation of the competitiveness of future teachers of mathematics. Research methods: analysis of scientific literature, systematization (to understand the key concepts of the study), generalization (to form author's conclusions). We identify four groups of socio-pedagogical preconditions for the formation of the competitiveness of future mathematics teachers. The first group is associated with changing the paradigm of education, the formation of a new concept of education that meets the needs of the individual, and dynamic society in the context of the introduction of innovative learning technologies. The second group is due to the peculiarities of the development of the information society: an increase in the volume of information produced, an increase in information consumption, and the development of new information technologies. The third group of preconditions is related to the integration processes of education: the development of a system of continuous education, the continuity of levels of education, the modernization of the educational process, and academic disciplines. The fourth group is caused by problems with the quality of education: an increase in the requirements for the level of professionalism of teachers, a change in the expectations placed on the education system, and the expansion of the educational opportunities of the individual. We have established that an important direction in improving the quality of education is to improve the mathematical education of young people.
PHILOSOPHY AND METHODOLOGY: DYNAMICS OF SCIENCE DEVELOPMENT
Authors: Rozman Iryna
Published: June 2022

The article reveals subject discussions on the development of philosophy and methodology of science. The peculiarities of philosophical and methodological disciplines, which give the opportunity to study the theory of knowledge and its structure, are determined. Emphasis is placed on the need to understand metaphysical, epistemological and ethical issues related to the practice and goals of modern science. Emphasis is placed on interpretation, which states that knowledge about the universe comes through scientific research. The process of development of science, which takes place gradually and dates back to antiquity, is singled out. Reflections on human knowledge through the figures of world-famous philosophers are presented and an explanation of the goals and methods of science is offered. The main focus is on the study of empiricists who have taken as their starting point the central task of understanding the great advantages of the natural sciences. In fact, they suggested that the search for the theory of the scientific method was carried out by Aristotle, Bacon, Descartes, et al. − can be done more thoroughly with the help of mathematical logic. Methods and results of the work of philosophy and methodology of science require constant replenishment of reliable knowledge about the world and man, but taking into account productive work on yourself. The focus is on the fact that some philosophers continue to work on issues that do not break the relationship with the natural sciences. Thus, exploring, for example, the nature of space and time or the fundamental features of life. The general philosophy of science, on the other hand, seeks to shed light on the general features of the sciences, continuing the research begun in antiquity using Aristotle's discourses on logic and method. It is noted that methodology is a rational-reflective mental activity aimed at studying ways to transform human reality-methods − rational actions that must be taken to solve a problem or achieve a goal. The application of methods is carried out in any field of scientific and cognitive activities. Methodology of science carries out research, search, development and systematization of methods used in this activity to obtain scientific knowledge and general principles that guide it. The main imperative of philosophical science is the need to teach people to think empirically, creatively, exploratoryly and independently.

Authors: Fushteі Oksana
Published: June 2022

The problem of virtual space violence is very relevant in Ukraine. The state's unstable situation and lack of proper punishment for cyberbullying and its prevention cause an increase in cases of this phenomenon. Cyberbullying is a problem that is rapidly spreading and causing irreparable damage to young people. The purpose of the article is to highlight the problem of cyberbullying and determine the main directions of the social worker’s work on the social prevention of cyberbullying among students. To achieve the goal of the study, a set of methods was used: analysis of social-pedagogical, psychological and pedagogical literature, comparison of scientific sources, which became the basis for determining the degree of scientific development of the problem, systematization in order to determine and clarify the basic concepts of research and existing scientific approaches to solving the specified problem, generalization - to formulate final provisions and conclusions. Theoretical study and empirical research allow us to draw the following conclusions regarding the concept of "cyberbullying" and examine its occurrence, causes, consequences and main directions of social prevention of cyberbullying. Therefore, cyberbullying is a type of bullying, but the specifics are the use of electronic communications. Cyberbullying can occur in various forms. Therefore, it can be classified into eight types, namely, disputes, or fleming, assaults, and constant debilitating attacks, slander and restatement, impostor (impersonation of oneself into another person), erase confidential information and spread it, alienate, cyber-harassment, and hepisleping. Preventive work is carried out in two directions. The first area is associated with the development of technical means that restrict unwanted content (filters, censorship), which provides social networks and websites "complain" buttons, as well as setting up the privacy of personal accounts. This area includes the creation of a system of rapid response of content providers and services, law enforcement agencies, communication operators for illegal activities and the Internet. The second area of cyberbullying prevention involves teaching Internet users the basic rules of security and correct behavior towards other community users. On the basis of theoretical study and empirical research, the main directions of social prevention of cyberbullying were revealed and the project "Social prevention of cyberbullying among young people in the Internet space" was developed

Authors: Hirniak Svitlana , Rozlutska Halyna
Published: June 2022

The study of the chapter «Word building» is important in the linguistic and speech development of pupils. Acquaintance of junior schoolchildren with the morpheme word building opens wide opportunities for systematic broadening, clarification of children's vocabulary, mastering one of the ways to reveal the lexical meaning of the word. According to the set goal the article summarizes and characterizes the basic requirements to the chapter «Word building», which are provided by the current program from the Ukrainian language for primary school students; effective methods and techniques of forming such concepts as word stem, ending, root, prefix, suffix in junior schoolchildren are determined; the tasks which will promote the development of communicative skills of junior pupils during studying a morpheme word building in elementary school are offered. The purpose of the research is to characterize the peculiarities of studying the morpheme structure of a word and word formation at Ukrainian language lessons in primary school, namely: to generalize program requirements (content and scope) from the chapter «Word building» declared in the current Ukrainian language program for primary school students and characterize the most productive methods and techniques of forming basic concepts such as word stem, ending, root, prefix, suffix; substantiate the communicative orientation of these lessons. The methodology of the research is complex, which consists in the use of general scientific, pedagogical and linguistic methods. Methods of analysis and synthesis, idealization (abstraction), generalization, induction and deduction have been used, which together helped to reveal the declared research topic and establish the peculiarities of the work on the chapter «Word building» in the 3rd grade of primary school. In the research it has been established that systematic and creative work on the semantics of the word during the elaboration of the chapter «Word building» helps to develop and increase pupils' interest in the Ukrainian language, teaches practical use of word-formation tools of the native language; promotes orthoepic and orthographic literacy, the formation of speech self-control and the development of communicative skills, as well as increasing interest in learning the Ukrainian language.

Gross Primary Productivity (GPP) is the core component of the terrestrial and global carbon cycle and Earth’s climate research. In this study, GPP estimation was performed with the Boreal Ecosystem Productivity Simulator (BEPS) model to check its performance for hemi-boreal forests on the example of the Soontaga area in Estonia. The model was run by using a combination of remote sensing (leaf area index (LAI), clumping index) and meteorological data inputs (air temperature, global radiation, air humidity, precipitation and wind speed). The results were validated against GPP derived from the available flux tower measurements. The spatial representativeness of the site was evaluated using multiple spatial thresholds (500 m–2 km), as well. We found that the BEPS model can track the GPP changes with the season and inter-annual variation very well in a coniferous hemi-boreal forest, given that good quality input data are provided.

We investigated the distribution of extractive, phenolic, and polysaccharides content of young S. mahagoni trees aged 1 to 5 years. The wood powder materials in two vertical positions (bottom and top) were successively extracted using n-hexane, methanol, and hot water solutions. The results showed that there was a significant interaction between the tree age and axial position in all parameters. The methanol and total extractive content decreased significantly from 1 to 3-year-old at the top part. In contrast, the amount of hot water and total extractive increased significantly from 3 to 4-year-old trees at the bottom part. Furthermore, a significant increase was also found at the bottom heartwood for hexane, methanol, and the total extractive from 4 to 5-year-old trees. The reverse trend was observed in the polar fractions (methanol and hot water) at the top of the trees. Generally, the extractive pattern tends to decrease from bottom to top with the highest proportion of methanol extract (70% based on the total extractive weight), and it increased from sapwood to heartwood. The total phenolic content (TPC) and total soluble polysaccharides (TSP) generally increase with tree age (except for TSP from 2 to 3-year-old trees at the top part). The high content of TPC in the heartwood and TSP in the sapwood indicated the process of heartwood formation. In addition, a drastic decrease in the methanol extract and TSP at the age of 3 years at the top indicated that the TSP was transferred from top to bottom for the heartwood formation at the bottom part of 4-year-old trees.

Estimations of forests’ carbon sequestration capacity relies on proper assessment of the eddy covariance measurement mast’s footprint. Harsh winter temperatures in Estonia lead to ice formation on 3D sonic anemometer sensor heads and thus induce measurement gaps in the data. To maximise data availability, we use a smart heating algorithm to minimise ice formation on the anemometer sensor heads. Here, we studied the temperature distribution of ice formation on the measurement instruments. Three major temperature ranges were found, between 0°C and −3°C, which is the most abundant temperature range for ice formation, and two temperature regions with peaks around −10°C and −20°C. Our algorithm to prevent ice formation led to very short median heating intervals of about 25 to 30 seconds.

In the greenhouse, mixed inoculation of Tetraclinis articulata (Vahl) Mast.) with Rhizoctonia solani Kühn and Fusarium solani (Mart.) Sacc. caused remarkable damping-off and root rot compared to simple inoculation with one of the two pathogens. Root and stem infections caused significant reduction in plant growth. Root system total length was reduced by 36 to 43% and shoot height losses by 28 to 39%. Plants inoculated by one pathogen were shorter than control plants or inoculated plants by both pathogens. Disease severity ratings for plants infested with the pathogens mixture also were greater than with either pathogen alone up to 62 days post-inoculation. R. solani and F. solani interact synergistically, causing severe damping-off and root rot in T. articulata seedlings.

The study material of Scots pine sample trees originated from five different forest site types (Cladonia, Calluna, Myrtillus, natural raised bog and drained raised bog) in Estonia. Altogether, 60 trees were sampled from 10 stands. From these, test disks and sample blocks (1.2 m in length) were cut at 1.3 m height, 1/2 of tree height and 3/4 of tree height. We analysed the effect of forest site type on the growth of tree ring width, proportion of late- and heartwood, oven-dry density, bending and compression strength and wood hardness. Wood properties in stands of the same age showed great variability. Significant differences were found in the wood properties between site types. Wood density and strength characteristics were higher in samples from heath site types than from the sites more optimal for pine (e.g., Myrtillus). The quality of the wood from peatland stands was lower than from trees grown on mineral soil. The decreasing trend in strength properties towards the top of trees was steeper in the wood formed under poor nutrient conditions. Latewood proportion increased with tree age. However, in the case of equal latewood percentages, heartwood density was higher than sapwood density.

Our work is part of the ex situ conservation of the Atlas cedar (Cedrus atlantica (Manetti ex Endl.) Carrière), a threatened and endemic Pinaceae of the Maghreb. Our objectives are to evaluate the viability of seeds from three Algerian cedar groves ecotypes (Thienet El Had, Chelia, Chrea) by the 2,3,5 triphenyltetrazolium chloride (TZ) test and to elucidate the effect of continuous temperatures (15°C, 20°C, 25°C) on their germinative capacity. Moreover, the effects of some physicochemical pretreatments in breaking dormancy and improving germinability were estimated on the seeds of the cedar grove of Thienet El Had. In addition, in the same ecotype, the water stress, as simulated by using the PEG6000 (0 to −2.20 bar), was induced upon seed germination. Results of the TZ test showed variability in seeds’ viability among the three ecotypes with rates of 60, 85 and 90% in those of Chelia, Chrea and Thienet El Had, respectively. However, germination tests revealed the existence of partial dormancy in all tested seeds. Dramatic differences in the degree of dormancy were noted among the three provenances investigated. Untreated seeds of the three ecotypes exhibited maximum germination at 20°C: Thienet El Had (52%), Chelia (32%) and Chrea (7%). The final germination percentage was as high as 76% in seeds soaked in hot water (80°C) for 5 min followed by 56% in seeds treated with GA3 (150 ppm). The increase in water stress regularly decreases germination with a tolerance threshold corresponding to −2.2 bar.
