Authors: Emelyanova O. Yu. , Tsoy М. F. , Masalova L. I.
Published: October 2024

Background. Human health security is an important goal of contemporary society. The combination of beneficial properties in Juglans nuts makes them one of the most valuable plant genetic resources, capable of ensuring a wholesome supply of nutrients required by the human organism. The Persian walnut (Juglans regia L.) has the largest set of useful agronomic traits among the representatives of the genus, except for winter hardiness. Its cultivation in areas farther to the north from the conventional area of distribution for commercial walnut orchards would be possible if Juglans spp. with higher resistance to unfavorable climate conditions could be involved. Interspecies hybridization can be used to increase winter hardiness in walnut. The objective of this study was to analyze the gene pool of Juglans L. and screen its bioresource collection at the arboretum of the Russian Research Institute of Fruit Crop Breeding (VNIISPK) in the context of useful agronomic indicators promising for plant breeding and landscaping. Materials and methods. The study was carried out in the VNIISPK arboretum (Orel Province, 53°00’N, 36°00’E) where 7 Juglans spp. are maintained. Results and conclusion. The results of the screening highlighted J. mandshurica Maxim., J. cordiformis Maxim., and Vekhov’s hybrid (J. cinerea L. × J. mandshurica Maxim.) as the most resistant to adverse environmental effects. They are recommended for use in plant breeding and landscaping programs under the conditions of Central Russia. A seedling of cv. ‘Astakhovsky’ demonstrated the best agronomic indicators among the Persian walnut (J. regia) genotypes. It can be used by breeders to develop new cultivars with useful agronomic traits for the environmental conditions of the region of study.

Published: October 2024

Background. The ever increasing anthropogenic impact on natural populations of rare and, especially, endangered plant species has recently become even more forceful. Therefore, the finding of a small black currant population representing sect. Eucoreosma (Spach) Jancz. within a natural environment in the south of Primorsky Territory appears highly important. Previously, none of the black currant species was recorded as occurring in this area. Materials and methods. Plants from the new locality were compared with accessions of Ribes nigrum L., R. ussuriense Jancz., R. pauciflorum Turcz. ex Pojark., and R. fontaneum Boczkarn. using morphological and molecular genetics techniques. Results and conclusion. A molecular genetics analysis of two chloroplast DNA fragments excluded any association of the discovered plants with R. nigrum or R. fontaneum. Meanwhile, no differences in chloroplast DNA fragments were found between these plants and R. ussuriense and R. pauciflorum accessions. A number of morphological features attested to a possibility to attribute the finding to the rare species R. ussuriense: its isolated localities had previously been reported in southern Primorsky Territory. The differences in chloroplast DNA fragments between the Siberian/Far Eastern species R. pauciflorum and the European/Siberian species R. nigrum make doubtful their possible fusion, based only on morphological characters, and require further studies.
Interspecific hybridization and cell engineering of lettuce (Lactuca L.)
Authors: Zagnukhina N. A. , Kurina A. B.
Published: October 2024

Lactuca sativa L. is a leafy vegetable crop of the Asteraceae family, widely cultivated throughout the world. The main breeding trends for lettuce include higher yields, better taste quality, earliness, and resistance to abiotic and biotic stressors. Some wild Lactuca spp. have actively been employed by lettuce breeders as donors of resistance to various diseases. Conventional and biotechnological breeding methods are both currently used to develop new lettuce cultivars. This is an overview of the main advances in the production of interspecific Lactuca hybrids, including the use of cell and tissue culture techniques, and genetic engineering. Studying artificial hybridization and natural populations makes it possible to identify evolutionary relationships among various Lactuca spp. Somatic hybridization is an overlooked but promising technology in Lactuca breeding: it allows a breeder to obtain a wider range of variations, and is beyond the strict control by GMO laws. This technique faces problems associated with complicated protoplast regeneration and the loss of reproductive ability in hybrids. Genome-editing methods are more effective and better controllable, but society is still wary of any interference with the plant genome and legally regulates the sale of GM products as food. Thus, researchers are challenged with the task to improve these techniques.
The use of the species Triticum petropavlovskyi Udacz. et Migusch. to expand the genetic diversity of spring bread wheat
Authors: Druzhin A. E. , Sibikeev S. N. , Andreeva L. V.
Published: October 2024

Background. The species Triticum petropavlovskyi Udacz. et Migusch. has a number of positive traits, but has rarely been used in breeding programs to improve bread wheat cultivars. The introgression of genetic material from this species into the Triticum aestivum L. gene pool will not only expand the genetic diversity of bread wheat with a set of traits valuable for breeders, but also help to analyze the expression of genes from T. petropavlovskyi in a new genetic environment. Materials and methods. Spring bread wheat lines L163 and L164 produced with the participation of bread wheat cv. ‘Voevoda’ and an accession of T. petropavlovskyi were target materials of the study. Conventional methods were applied to perform phenological, phytopathological, genetic, and bread quality evaluations. Statistical processing of the resulting data was carried out using the Agros-2.10 software. Results. L163 and L164 were studied for their morphological and phenological indicators, resistance to pathogens, productivity, and grain quality. Differences in a number of traits between the lines and the recipient cultivar were observed. The introgression of the T. petropavlovskyi genetic material into bread wheat showed both positive and negative effects on some agronomic characteristics. L163 was identified for its resistance to the pathogens of leaf rust and powdery mildew, and tolerance to cereal aphids. It combined high productivity with an increased grain protein content compared to the recipient cultivar. In addition, this line demonstrated good rheological properties of its dough. Conclusion. Merging genetic materials from T. petropavlovskyi and bread wheat cv. ‘Voevoda’ made it possible to produce lines with a set of positive characteristics. The selected line, L163, combined effective resistance to a number of diseases, high grain productivity, and good breadmaking qualities, so it was included in the breeding process.

Published: October 2024

Background. Soybean is the main supplier of complete vegetable protein and oil. Prior to the emergence of new early-ripening cultivars, this crop was not cultivated in Irkutsk Province. Its introduction into the area requires a detailed study of agricultural practices, primarily the choice of optimal sowing dates. Materials and methods. Soybean cv. ‘Barguzin’, late-ripening under the conditions of Irkutsk Province, and early-ripening accession 15 served as the research objects. Field studies were carried out in 2019–2021. There were four sowing dates, from the first ten-day period of May through the first ten-day period of June. Results and conclusion. Cv. ‘Barguzin’ appeared highly productive under the climate of Irkutsk Province (its average seed yield in 2019–2021 was 2.7 t/ha), but its productivity was significantly influenced by weather conditions and sowing dates (seed yields varied from 1.4 to 3.6 t/ha). The optimal sowing times for this cultivar are the first and second ten-day periods of May. Early-ripening accession 15 was characterized by more stable yield values in the studied years (average productivity was 2.4 t/ha, minimum 1.9 t/ha, and maximum 3.2 t/ha). The preferred sowing times for this accession are the second and third ten-day periods of May. The case study of two soybean genotypes differing in maturation schedules revealed the need for individual selection of sowing dates. It was shown that the early-ripening soybean genotype imposed less stringent requirements on the choice of sowing dates.

Published: October 2024

Background. Studying the genetic diversity of ex situ barley accessions under contrasting environmental conditions (humid with a lack of heat, favorable, arid, etc.) makes it possible to assess them according to the duration of the growing season, resistance to lodging, potential productivity, drought resistance, grain quality, and environmental plasticity. Materials and methods. The results of an 8-year trial (2016–2023) of 11 spring barley accessions of Belarusian origin in the northern forest-steppe zone of Tyumen Province are presented. The experiments followed the protocols adopted for the state variety trials. An SKS-6-10 seeder was used for sowing, the plot area was 5 m2 , and cv. ʻAbalakʼ served as the reference. The seeding rate was 550 viable seeds per 1 m2 . Results. A majority of the studied accessions matured later than the medium-ripening reference cultivar. Weather conditions during the growing season in the Northern Trans-Urals had a decisive effect on the harvest formation, protein content and starch content in barley grain (74.6%, 70.8% and 81.8%, respectively). The effect of the genotype on these indicators was 7.9%, 17.5% and 6.2%, respectively. Starch content also depended on the genotype × environment interaction (9.7%). Fat content was almost equally affected by the genotype (25.1%) and the environment (26.7%). The genotype × environment interaction was more significant (31.2%). Conclusion. The following sources were identified among the tested cultivars: ‘Vodar’ (high yield, drought tolerance, etc.); ‘Magutny’ (high yield, and environmental plasticity); ‘Khago’ (large grain, low hull content, and increased protein and starch content levels); ‘Lipen’ (high test weight, increased starch content, and environmental plasticity); ‘Fobos’ (drought tolerance, and increased protein content); ‘Dublet’ (lodging resistance, and increased protein content); ‘Taler’ (reduced protein content, and environmental plasticity); ‘Pospekh’ (reduced protein content).
In vitro clonal micropropagation of selected Malus niedzwetzkyana Dieck forms demonstrating high resilience when introduced into urban environments
Authors: Belanova A. P. , Zaytseva Yu. G. , Lyakh E. M.
Published: October 2024

Background. Currently, the use of an interdisciplinary approach based on a combination of traditional introduction methods and clonal micropropagation techniques makes it possible to solve one of the key problems of introduction – the establishment of bioresource collections consisting of selected plant accessions with valuable agronomic traits and resistance to unfavorable urban environments. Materials and methods. A plant introduction study resulted in identifying seven specimens of Malus niedzwetzkyana Dieck with resilience to urban environments, high rate of crown development, and longevity. They served as source material for the development of a clonal propagation protocol and in vitro preservation of selected genotypes of this species. Results. It was shown for M. niedzwetzkyana that the most favorable time for taking its plant material for introduction into in vitro culture is the beginning of the active growth of vegetative shoots after flowering. The most optimal sterilization technique for such plant material was a stepwise regime using alcohol, sodium hypochlorite, and silver nitrate: it provided from 50 to 70% of sterile explants and the maximum percentage of meristem proliferation. Combining 0.8 mg/L of benzylaminopurine (BAP) with 0.14 mg/L of indole-3-butyric acid (IBA) at the stage of microclonal propagation ensured a significant increase of the reproduction coefficient (on average up to 5.3 ± 0.7) and an improvement in morphometric parameters of microshoots; the maximum frequency of shoot proliferation was 100%. The yield of shoots adapted to ex vitro conditions was 90%. Conclusion. The developed clonal micropropagation protocol made it possible to introduce selected M. niedzwetzkyana forms into in vitro culture and reproduce them in order to set up a resource base for further fundamental and applied research into the system of the genus Malus Mill.

Published: October 2024

Background. Peanut is one of the most important oil crops for food purposes. Natural peanut butter contains two unsaturated fatty acids, oleic and linoleic, which make up to 80% of the total fatty acid content in peanut oil. The quality of oil depends on the ratio between these two acids. Analyzing the diversity of oil content and fatty acid composition in peanut accessions preserved at VIR and assessing the effect of soil, climate, and other factors on these characters is vital for the development of new peanut cultivars rich in oil. Materials and methods. Peanut germplasm accessions were studied for their biochemical composition of fatty acids and the content of oil and protein. The accessions were reproduced for three years (2019–2021) at two ecogeographic locations: in Krasnodar Territory, and Astrakhan Province. Cv. ‘Otradokubansky’ was used as a reference. ANOVA was applied for statistical data processing. Results and discussion. The percentage composition of 18 fatty acids was calculated in peanut oil, with oleic and linoleic acids dominating. The content of oleic acid depended on the genotype for 42–53%, and that of linoleic acid, for 50–71%. The latter was also influenced by the place and year of cultivation. The ranges of variation over the three years of studies in Krasnodar Territory were 35.4–57.6% for oleic acid, and 18.3–38.1% for linoleic acid, whereas in Astrakhan Province they were 33.4–51.2%, and 30.9–42.7%, respectively. Under unfavorable conditions, the content of oleic acid in peanut prevailed. The oil content depended on the genotype for 81%, and its percentage was 32.0–44.4%.

Published: October 2024

Vygostky's learning theory discussed in this article was pioneered by a figure named Lev Vygotsky who argued that learning is a social process. According to him, children have expertise in developing knowledge starting from social interactions with their social environment. One of the applications is cooperative learning conducted in a group, which contains a group of children who have different abilities to work together and help each other. Vygotsky's theory has the advantage that students are able to think together in solving problems so that the problem can be solved, but it also has the disadvantage that the time needed is longer because of the different abilities of students. The writing of this article aims to find out the history of the Vygotsky theorist, the concept of Vygotsky theory, the implementation of Vygotsky theory in education and its influence in learning. The author uses literature review and questionnaire methods in writing this article. The results obtained from this study were that some of the respondents felt helped by the implementation of Vygotsky's theory in learning, while others did not feel helped or neutral.
DETERMINATION OF FERTILITY OF FIRST CALVING COWS UNDER DIFFERENT HOUSING
Authors: Admin O. E. , Admina N. G.
Published: October 2024

The best fertilization rate of firstborns was established at the farm “Kutuzivka” under free housing, it was 11% times higher than at the farm “Agroprogres”, and 7% higher than the farm “Dekabrystiv”. The influence of the "farm" factor – 1.0% was probable (p < 0.001). In our opinion, the higher percentage of fertile inseminations of firstborns is explained by the use of an automatic system for determining sexual desire at the farm "Kutuzivka".The season of the year was the most influential factor in the fertilization of the first-born cows among the factors of the external environment. The largest number of inseminations of first-borns at farm “Agroprogres” was in the summer (28%), and the lowest in the winter (23%). On the farm of the farm “Dekabrystiv”, a greater number of inseminations were also carried out in the summer (30%) months, and the smallest share of inseminations – in the winter (21%). The nature of this impact is explained not by the state of the environment, but by the housing technology and feeding animals.
During the first insemination after calving, a slightly lower percentage of fertilization of first-borns was observed in all studied farms. During the second insemination, it increased by 4% in the animals of the farm “Agroprogres”, by 7% in the farm “Decembrists”, by 3% in the farm "Kutuzivka". In the subsequent growth of the number of insemination of firstborns in the first two farms did not lead to probable changes in fertility. At the same time, the animals of the the farm "Kutuzivka", starting from the 5th insemination, were fertilized by 11–23% less than from the second insemination. The influence of this factor on the effectiveness of insemination of cows was improbable in the farm “Agroprogres” and amounted to 0.7%, in the farm “Dekabristov” and the farm "Kutuzivka" 0.8%. It was established that in all experimental farms, the number of artificial insemination after the first calving of cows is not the main factor that determines its fertility. The main factor related to the efficiency of insemination is the stage of lactation. Correlation coefficients of the lactation day with the number of artificial insemination in experimental farms ranged from +0.545 to +0.723 and with the daily productivity of first-borns equaled from +0.156 to +0.383. Low fertility in the first 90 days of lactation is primarily due to a high milk dominance, possibly a negative energy balance during this period of lactation.
INTENSITY OF GREENHOUSE GAS FORMATION DUE TO LIVESTOCK FARMING ACTIVITIES – AS AN ENVIRONMENTAL FACTOR
Authors: Nykyforuk O. V. , Zhukorskyi O. M. , Boltyk N. P.
Published: October 2024

According to numerous expert assessments by international organizations and specialists, animal husbandry makes a significant negative contribution to global climate change due to the emission of greenhouse gases (GHG), which are formed at different stages of livestock production as a result of various chemical and biological processes in the body of animals and in livestock waste. The domestic animal husbandry is developing mainly due to the intensification of production in the industry, but traditional farming methods as well as small-scale production in the individual sector also take place. Since the use of various technologies in animal husbandry has different effects on the level of environmental pollution and GHG emissions, the aim of the research was to study the differences in the intensity of GHG gas formation by one animal reared with individual features of animal rearing technologies and business activities. The intensity of gas formation and emission of CH4 and N2O in typical farms for pork production and milk production by one animal reared was determined, analyzed and substantiated. A significant variation in this indicator was found depending on the individual economic and technological features of the studied farms. The average weighted annual intensity of CH4 emission from animal manure in pig farms varied within the range of 0.95–25.71, in cattle farm – 2.74; CH4 from intestinal fermentation of dairy cows – 110.8–148.4; N2O (direct) in pig farms – 0.0–0.106, in cattle farm – 0.229; N2O (indirect) in pig farms – 0.071–0.097, in cattle farm – 0.174. The emission intensity is characterized separately in each age and sex group of animals in the herd structure of farms and the average weighted emission intensity in pork producing farms depending on the season. Based on the research results, it is proposed to use the generalized average annual indicator of greenhouse gas emissions per one average weighted animal reared (kg/head/year) as an indicator of the environmental load of livestock farms on the environment, which will allow planning production volumes with minimal environmental risks in the context of climate change.

Authors: Pavlenko Yu. M. , Kompanets I. O.
Published: October 2024

Impact research of the duration of service period on the longevity traits of Holstein and Ukrainian Black-and-White dairy cows was conducted in the herd of private enterprise "Burynske" in Sumy district. It has been established that the milk yield of cows for 305 days and full lactation according to the assessment data of the first, third and best lactations and, in general, for the entire life, grew under the condition of increasing the duration of service period to the level of 140 days, regardless of breed. A further increase in the duration of service period for 141 days led to a decline in the above-mentioned traits. The highest lifetime milk yield was obtained from a group of cows with a service period length of 121–140 days, which amounted to 31955 ± 606.7 kg in Holsteins, and 30188 ± 624.4 kg for Ukrainian Black-and-White dairy breed. Against the background of increase in the duration of service period, rising rates of lifetime, productive use and the number of used lactations was observed in cows of experimental breeds. However, the yield per day of life and productive use decreased in groups of Holstein breed with a service period of ˃ 80–161 < days, from 14.6 to 10.3 kg and from 24.7 to 14.6 kg, respectively. In the groups of cows of the Ukrainian Black-and-White dairy breed with the duration of service period ˃ 80–161 < days, corresponding reduction in milk yield per day of life and productive use amounted to 13.1–9.5 and 21.9–13.2 kg. A direct, medium-level, reliable relationship between the service period length and the traits of lifetime, productive use, milk yield and milk fat during life was revealed, which was within the range of r = 0.193–0.311 in Holstein cows and Ukrainian Black-and-White dairy r = 0.145–0.251. An inverse and highly reliable relationship was found between the duration of service period and the milk yield per day of life and productive use in Holstein cows (r = -0.268 and -0.383) and Ukrainian Black-and-White dairy breed (r = -0.255 and -0.325). The strength of influence the duration of service period of cows on their lifespan, productive use and number of used lactations was 22.4–27.5% for Holstein breed, and 21.4–24.3% for Ukrainian Black-and-White dairy breed. Traits of lifetime milk productivity of Holstein cows depended on the duration of service period by 12.2–31.3% and of Ukrainian Black-and-White dairy cows by 13.4–28.9%.

Coke dry quenching: utilisation of excess circulating gas
Authors: Kogtin A.A.
Published: October 2024

The article is devoted to a practical solution to the problem of improving the environmental safety of a coke dry quenching unit by means of a new technology developed to reduce CO and coke dust emissions by introducing of the utilisation of excess circulating gas using a special utilisation unit, the main element of which is a special utilisation boiler. It is shown that the need to discharge harmful substances into the atmosphere during the operation of the coke dry quenching unit is associated with the fact that during the operation of the unit, repeated circulation of gases through hot coke leads to a change in the gas composition in the direction of increasing the amount of carbon monoxide (CO). This makes the plant explosive and the gas highly toxic. To reduce the explosion hazard of the plant, it is necessary to reduce the concentration of combustible components in the circulating gas. This is done by diluting the mixture with nitrogen. This article discusses the method developed by GIPROKOKS to utilise excess circulating gases by burning CO to CO2 using a special utilisation unit. The equipment of the utilisation unit can be located directly in the boiler house of the coke dry quenching unit or in a separate building near the coke dry quenching unit. The operation of the utilisation unit is controlled by a modern process control system. The concentration and gross carbon monoxide emissions are reduced in a special reactor. In the process of refining the implemented technology, it became necessary to make changes and improve some solutions. In particular, the operation of the gas path of the unit was changed, which increased the potential for receiving excess circulating gas, stabilised the combustion mode and became a key solution to ensure the aerodynamic operation of the coke dry quenching unit. A mixing device was also installed at the circulating gas inlet to the waste heat boiler, which, by controlling the flow rate and composition of the circulating gas, allowed to stabilise the reactor operation and somewhat improve the conditions for the utilisation (combustion) of combustible components when circulating gas of ‘ballasted’ composition is supplied. It is shown that the implementation of this technology by SE “GIPROKOKS” can significantly reduce the concentration of harmful substances and provides additional steam generation, which can be used for the technological needs of the enterprise or for generating electricity.

Authors: Trembach T.F. , Mezentseva M.V. , Radychuk I.О.
Published: October 2024

The article considers the issues related to the use of large volumes of water in the technological processes of coke production, which results in the generation of a large amount of polluted wastewater of different origin and properties. It is noted that a separate wastewater sewerage system is used at coke plant allows differentiated solutions to the methods of treatment of wastewater of different composition and the fullest use of treated wastewater for the production needs of the enterprise. Water supply to the main water consumers at the coke plant is applied according to the reverse scheme. The article characterises the quantitative and qualitative composition of wastewater coming from different shops of coke production. The necessity of efficient purification of phenolic waters at a waste water treatment plant is considered, which is dictated by their further use according to the technological scheme in production. The analysis of the waste water treatment plant as a source of air pollution and the need to determine the quantitative and qualitative characteristics of pollutant emissions from the waste water treatment plant to assess the environmental impact are provided. The methods for determining pollutant emissions from waste water treatment plants, which are currently used at existing enterprises and in the design of waste water treatment plant facilities, are considered. The necessity of developing a methodology for calculating pollutant emissions from waste water treatment plants at coke production is substantiated. The list of basic initial indicators for performing mathematical calculations of pollutant emissions from waste water treatment plant facilities in coke production is established. The algorithms of mathematical calculations of the quantitative composition of pollutant emissions from the tank equipment depending on the characteristics of the technological process and design features of the waste water treatment plants tanks are presented. Keywords: coke production, wastewater, pollutant emissions, composition, treatment, waste water treatment plant, methodology. Corresponding author: Trembach T.F., e-mail: ozos@giprokoks.com

Published: October 2024

Systematic literature reviews are foundational for advancing knowledge across research domains, yet their labor-intensive nature often limits their availability and efficiency. As a result, researchers may resort to less structured approaches, which can compromise the rigor and reliability of findings. Current solutions are limited in scope, adaptability, and ease-of-use, particularly within the computing domain. To address this gap, we introduce ARC (Automated Review Companion), an open-source tool designed to automate and facilitate various aspects of Systematic Literature Reviews while preserving high standards of transparency and reproducibility. ARC is developed following a user-centered approach, iteratively refining it through interviews with a group of 20 diverse computing researchers. We then examined ARC's real-world adaptability by conducting a user study focused on diverse research use cases. We identify key design principles that improve the usability and effectiveness of research-oriented tools, contributing to a more streamlined and reliable research pipeline. ARC fosters an accessible and efficient research ecosystem by supporting FAIR principles and encouraging open, reproducible research practices.

This study explores using humanoid robots to improve the diagnosis and intervention of Autism Spectrum Disorder (ASD) through objective measures, gaze pattern analysis specifically. Traditional ASD diagnostic tools rely on subjective assessments, while our approach uses the iCub robot to provide quantitative metrics. In our proof-of-concept study, the robot engaged children in interactive games to assess mutual gaze. Results showed that neurotypical children maintained more eye contact compared to children with ASD. This highlights the potential of humanoid robots to offer objective, standardized measures that can improve the accuracy of ASD diagnoses and interventions.

Progress in machine learning and artificial intelligence promises to advance research and understanding across a wide range of fields and activities. In tandem, increased awareness of the importance of open data for reproducibility and scientific transparency is making inroads in fields that have not traditionally produced large publicly available datasets. Data sharing requirements from publishers and funders, as well as from other stakeholders, have also created pressure to make datasets with research and/or public interest value available through digital repositories. However, to make the best use of existing data, and facilitate the creation of useful future datasets, robust, interoperable and usable standards need to evolve and adapt over time. The open-source development model provides significant potential benefits to the process of standard creation and adaptation. In particular, data and meta-data standards can use long-standing technical and socio-technical processes that have been key to managing the development of software, and which allow incorporating broad community input into the formulation of these standards. On the other hand, open-source models carry unique risks that need to be considered. This report surveys existing open-source standards development, addressing these benefits and risks. It outlines recommendations for standards developers, funders and other stakeholders on the path to robust, interoperable and usable open-source data and metadata standards.

Autism Spectrum Disorders (ASD) often involve challenges in social communication, and various therapies are used to address these. This randomized, two-period crossover trial assessed the effectiveness of integrating Applied Behavior Analysis (ABA) with robot-assisted therapy to improve Theory of Mind (ToM) skills in children with ASD. Thirty-two children (mean age 7.53 ± 1.32 years, 7 females) participated. Group 1 received robot-assisted therapy first, followed by traditional therapy, while Group 2 had the reverse order. ToM skills were evaluated at three points: baseline (T0), after the first period (T1), and after the second (T2). Evaluators were blinded to the treatment conditions. Significant improvements in ToM were observed with robot-assisted therapy compared to traditional methods. A control group confirmed the robot's superiority over human actors in role-playing scenarios. No participants discontinued the study, highlighting the potential of integrating technology into ASD therapy.
Is Motivation Key? Scale Development and Validation of Integrative Digital Agency (IDA)
Authors: Kaesmayr Julia
Published: October 2024

Digital knowledge work is driven by technological advancements. Digital knowledge workers (DKW) continuously experience cognitions based on evaluative observations and emotions shaped by motivation and behavior while using digital resources. While existing domain-specific ability self-concepts can describe competences for coping with digital knowledge work, a representation of dynamics between dispositions and motivation is missing. Hence, the concept of Integrative Digital Agency (IDA) is suggested. IDA takes on domain-specific self-concepts related to digital resources, integrates digital agency, includes work motivation based on self-determination theory and maps them onto personal strivings. To evaluate the concept and identify the model, it was operationalized followed by field testing on two independent samples. Exploratory factor analysis identified a parsimonious hierarchical two-dimensional construct with four factors and eight items. Confirmatory factor analysis, performed twice, rendered the IDA8 scale adequate for field application. Providing insight into individuals' digital self-perceptions and motivation, the IDA concept offers a decision-making foundation for human resource management pertaining to organizational intervention while offering an anchor to foster digital competence in DKWs. The IDA8 scale developed in German has been translated into English pending validation. Conceptual and methodological limitations are discussed.

A growing body of research is connecting global environmental degradation to negative impacts on mental health and human flourishing. Meanwhile, international research and policy agendas are targeting the sustainable development of human health and flourishing. Here we argue that these research and policy approaches are too narrow, because they largely position the health and welfare of non-human species and ecosystems as instrumental to human flourishing. In contrast, we propose a novel approach, ‘ecological-collective-flourishing’ (e-co-flourishing), to inspire research and policy that situates human flourishing within the flourishing of non-human species and more-than-human ecosystems. We begin by clarifying what flourishing is, and how it is distinguished from other common concepts in global policy agendas, such as ‘wellbeing’, ‘health’ and ‘mental health.’ We next argue that e-co-flourishing research will require a paradigm shift in research design, to include dynamic, multi-scale and multi-dimensional metrics as well as interdisciplinary hypotheses that bridge the human and non-human sciences. Finally, we motivate and illustrate the incorporation of e-co-flourishing into research and policy through a case study, The Flourish School. Our proposal offers a disruptive research and policy agenda that will require intellectual humility and interdisciplinarity, as well as cross-fertilisation of policy, publication and funding structures to succeed. We invite others to join us in progressing e-co-flourishing for the good of all living things and systems on Earth.
A Systematic Review on Individual Prerequisites for STEM Learning in Augmented Reality - Suggesting the "L-Tech Triad" for Future Studies

Abstract The affordances of Augmented Reality (AR) make it well-suited for STEM learning. At the same time, individual differences, such as working memory capacity and spatial ability, are crucial for STEM. To understand how AR effects on STEM learning depend on individual differences, it is essential to follow the ATI (Aptitude-Treatment Interaction) perspective and investigate interactions between individual differences and AR- vs. non-AR conditions. This systematic review explored the extent to which individual characteristics are examined in AR research as predictors to further review if and how AR research in STEM education follows an ATI approach. Our findings reveal that from 2013 to 2022, k = 38 studies investigated the role of individual variables as predictors with only k = 5 studies considering how individual differences interact with AR vs. non-AR conditions. We discuss possible reasons for this gap and propose solutions, offering a study design framework to conduct AR studies considering the ATI perspective.
Assessing Daily Life Activities with Experience Sampling Methodology (ESM): Scoring Predefined Categories or Qualitative Analysis of Open-Ended Responses?
Authors: Stadel Marie , Langener Anna , Hoemann Katie , Bringmann Laura Francina
Published: October 2024

One domain frequently assessed in Experience Sampling Methodology (ESM) studies is that of daily activities. This is often done with predefined (and unvalidated) categorical items, but can also be done using open-ended items. ESM researchers, however, lack tools and guidance in analyzing the obtained open-ended data. In the first part of this paper, we use data from a 28-day ESM study in which students reported their activities both categorically and open-endedly to compare these two assessment approaches. We additionally present participant preferences and reflections captured in exit interviews. In the second part, we illustrate the qualitative analysis process for open-ended ESM responses. We introduce a Shiny app facilitating the coding of qualitative text snippets and code enabling interactive exploration of (hierarchical) code structures derived from qualitative analyses. Our results highlight the advantages and limitations of both assessment approaches: while categorical items offer simplicity, they often lack specificity. Conversely, open-ended responses provide richer, more personalized data, making them particularly valuable in idiographic clinical applications and exploratory research. A combination of both formats may enable the most effective assessment. We hope the tools we provide encourage the further use and exploration of open-ended ESM assessments.
Not all verbal labels grease the wheels of odor categories

Published: October 2024

Language is known to play a crucial role in influencing how humans perceive and categorize sensory stimuli, including odors. This study investigated the impact of linguistic labeling on odor categorization among bilingual participants proficient in Chinese (L1) and English (L2). We hypothesized that L1-like linguistic labels would more robustly propel the learning of new olfactory categories compared to a condition without language, and more familiar labels would better support odor category learning. The analysis focused on comparing learning trajectories and odor categorization performance of four groups, three in which odors were paired with different sets of verbal labels and a control group that categorized odors without any verbal labeling. Following four days of intensive training, the results showed that the groups with verbal labels numerically outperformed the control group, and that the less familiar the labels sounded the more successful categorization became. However, between-group differences did not reach statistical significance. These findings, while not conclusively supporting our hypotheses, provide insights into the complex relationship between linguistic familiarity and odor category formation. The results are nested within Ad Hoc Cognition, highlighting that variations in linguistic familiarity may not induce robust enough contextual changes to differentially affect how odor categories are formed.
